Why Isn't My Vehicle's Air Heater Working?

Grand Rapids has already seen its first snowfall even before the official start of winter. Though it was short-lived, there will be plenty more to follow before spring arrives in West Michigan. Therefore, making sure your vehicle's heater is in good working order makes the difference between a comfortable winter, or bundling up every time you go for a drive. Not to mention, you'd have difficulty clearing the windshield every morning!

This article briefly explains how your vehicle's heater works, plus some common issues within its systems that cause your heater to stop blowing warm air.

How Your Vehicle's Heater Works: In A Nutshell

Ever wonder how your vehicle makes the heat that comes out of the vents? If you're familiar with how radiators work, it's quite simple.

When your engine is running, it produces heat. So much of it in fact that if the heat isn't released, the engine will warp and damage itself. That's why you have a radiator and coolant. The coolant is pumped through a series of hoses that absorb the heat and as it passes through the wound-up pipes of the radiator, a fan cools the liquid coolant and blows it out the front grille.

However, there is a smaller radiator toward the back of the engine called the heater core, which does the same thing but the heat is sucked out of the engine bay and blown into the cabin with fans.

Why Isn't My Heater Blowing Warm Air Anymore?

If your heater isn't working anymore, there could be any number of reasons. Rest assured that the highly-trained and friendly technicians at the Borgman Service Center will get to the bottom of it, but here are a few common causes.

Your Coolant Levels Are Low

As we explained above, coolant passing through the heater core is what supplies the heat to the cabin of your vehicle. If your coolant level is low, it could be that you have a leak somewhere or your engine needs a new gasket. If this is the case, coolant is being allowed to mix with the engine oil and is burning up with the gasoline. You might notice thick, white, sweet-smelling smoke from your tailpipe if this is the case.

Coolant can degrade over time, but if you're filling the coolant reservoir often, it is a critical issue that needs to be addressed by the Borgman Service Center as soon as possible.

It Could Be An Issue With The Heater Core Itself

If your coolant level is fine, there might be a clog within the heater core's tubes. A flush might resolve the issue, but replacing the heater core can be an expensive repair.

If your heater core is going out, you might notice a fog, or a sweet, almost fruity smell coming from the vents. Other symptoms include the engine overheating or unexplained coolant loss.

Alternatively, a faulty thermostat could be causing the cooling system to not switch lines and supply the heater core with hot coolant. Luckily, the thermostat is a relatively inexpensive fix.

It Could Also Be A Problem With Your Controls

If your temperature-selector, whether analog or digital, isn't getting the signal from the dial to your vehicle, then you won't get any hot air. Or, you might only get hot air when you don't want it - such as during the summer.

This can be caused by debris gumming up the inner-workings of the dial or some fault within your head unit. If you suspect this might be the case, let us know and our technicians will look into it.

2026 Towing Guide: Pro Tips For a Successful Summer Trip

The summer towing season is finally here! At Borgman, we know the West Michigan summer is best enjoyed with a boat, camper, ATV, dirt bikes, or whatever else you want to bring with you to your favorite getaway. While getting out of town and enjoying the warmer weather is great, making sure you tow your trailer safely is important, too. Take a look at our revised towing guide for a quick tutorial (or refresher) on what to do, what not to do, and then head to the Borgman Service Center for a pre-vacation checkup or to have new towing equipment installed! more 2026 Towing Guide for West Michigan Adventurers Before Hitting The Road: If you're reading this in preparation for towing for the first time, it's worth visiting Borgman to ensure your vehicle is properly equipped. We will make recommendations about which parts will be necessary to tow your trailer or camper safely, then order the parts for you and install them as soon as possible. That way, your vehicle spends less time in the shop and more time out on the road, and you're towing with confidence. To see what parts are available for your vehicle and the current pricing, visit Accessories.Ford.com. Finally, even if your vehicle is properly equipped and you're a towing veteran, getting a quick checkup before setting out is critical for everyone's safety and prolonging the life of your vehicle. Take a look at our Service Specials and Schedule An Appointment today. Weight Distribution For the best braking and handling performance, your vehicle's load must be properly distributed - keeping the center of gravity as low as possible. Approximately 60% of the allowable cargo weight should be in the front half of the trailer, and the rest in the rear (consult limits of tongue load or king pin weight!) The load should be balanced from side to side, too, and must be firmly secured to prevent shifting during cornering or braking. Backing Up With A Trailer If you've never done this before, you might want to get some practice in before needing to do it "out in the wild." All you need to do is back up slowly, and have someone help you by standing behind the trailer guiding you in. Put one hand at bottom of the steering wheel and move it in the direction you want the trailer to go. Make small steering movements - the trailer will move more than you'd expect. Remember, you can always go forward to readjust or start over. Backing up a trailer can be tricky! Braking Remember, your vehicle is going to be heavier so it'll take longer to stop. Some Ford Vehicles equipped for towing will include electronic braking assistance for your vehicle and your trailer if it has brakes, but it's still good practice to drive more defensively. Allow more space between you and the vehicle in front of you to give yourself time to stop safely. If your trailer starts swaying, the easiest way to correct it is to gently speed up. If that's not helping and your vehicle is equipped with electric brakes and a brake controller, activate the trailer brakes with the brake controller by hand. Do not apply the tow vehicle's brakes as this can make things worse. Towing On Hills Downshift the transmission to assist braking when going down steep hills and to increase power (reduce lugging) when climbing hills. With the Ford TorqShift® transmission, simply select tow/haul mode to automatically eliminate unwanted gear search when going uphill and help control your vehicle speed when going downhill. Parking With A Trailer Whenever possible, vehicles with trailers should not be parked on a hill - even on a slight incline. If it can't be avoided, you can place wheel chocks under the trailer's wheels, following the instructions below: Apply the foot service brakes and hold Have another person place the wheel chocks under the trailer wheels on the downgrade side Once the chocks are in place, release the brake pedal, making sure the chocks will hold the vehicle and trailer Apply the parking brake Shift the automatic transmission into park or the manual transmission into reverse With 4-wheel drive, make sure the transfer case is not in neutral (if applicable) Acceleration And Passing The added weight of the trailer can dramatically decrease the acceleration of the towing vehicle - exercise caution. When passing a slower vehicle, be sure to allow extra distance. Remember, the added length of the trailer must clear the other vehicle before you can pull back in. Signal and make your pass on level terrain with plenty of clearance. If necessary, downshift for improved acceleration.

The Reduced Maintenance Needs of Your Ford Electric Vehicle

Getting behind the wheel of your first Ford Electric Vehicle is an exciting experience, especially with the warmer weather on the way. Among all of the perks of owning an EV, which include no tailpipe emissions, charging at home, and much more cargo space, one of the biggest people don't often consider is reduced maintenance costs. Electric Vehicles have far fewer moving parts when compared to their internal-combustion counterparts, and will never need things like oil changes, oil filter changes, fuel filters, spark plugs, radiator flushes, and more. However, there are still some features of your EV you should not neglect, and since service visits for oil changes are primarily where our techs spot other problems, it's paramount that owners bring their vehicles in for inspections on schedule. Here are some of the most important features of TVs that you should include in your maintenance regimen. Rotating and Replacing Tires This is perhaps the most obvious item on the list, but it's important to mention all the same. As your sole contact with the road, your tires need to be properly maintained to ensure your safety and maximize their lifespan. We recommend rotating your tires every other oil change at a minimum, but in this case, every 5,000 to 10,000 miles would be ok. Rotating your tires on a regular basis not only extends their lifespan but also allows our technicians to check for other subtle issues, such as uneven tread wear caused by poor alignment or worn suspension parts. It also gives us an unobstructed view of your brakes, basically amounting to a free inspection of your front end. Brake Pads, Rotors, Calipers, and Braking System Parts Brake maintenance is also very important for your safety and the safety of other drivers. Brakes use hydraulics to squeeze the calipers against the spinning rotor, which is locked to the wheel, slowing it down. Pads (or in rare cases, shoes,) help the caliper grip the rotor, so it's very important that all four of these pieces are inspected regularly. Many EVs are also equipped with regenerative braking, which uses the energy from slowing the vehicle down and feeds it back into the battery, leading to longer battery range and miraculously, longer brake life. While we urge owners to have their brakes inspected regularly, they will not need to be replaced or serviced nearly as often. Battery and Electric Motor Maintenance This will be a short section, as your electric vehicle batteries and motors will require little to no maintenance over the life of the vehicle. These components will last roughly the same amount of time as an internal combustion engine, though many experts predict they will last much longer. The best way to ensure this is to carefully follow the charging instructions in your owner's manual. Electric Vehicle Transmission The transmissions in electric vehicles do not have the same transmission as most gas-powered vehicles, though more and more are being equipped with something similar. A continually-variable transaxle, or CVT is a type of transmission that uses belts instead of traditional gears to transmit power from the engine to the wheels. Since the electric motors on EVs are more closely tied to the wheels, a different setup is required, but the principle is the same. These transmissions will need some maintenance over their lifetime, but not much. Be sure to carefully follow your recommended maintenance schedule, as the EV motors and transmissions are among the more expensive components of your electric vehicle. Shocks, Struts, and Suspension Components Just like gas-powered vehicles, electric vehicles will still need routine maintenance performed on suspension components, such as shocks, struts, and occasionally things like control arms, tie rods, and more. Regular tire rotations can usually catch these issues before they fully develop into expensive problems. Be sure to stay up-to-date on your alignments and inspections and you'll see costs on par with what you'd expect with a non-electric vehicle. Trust the Borgman Service Center For Your Electric Vehicle Needs Your electric vehicle has different maintenance needs than the vehicles we've grown accustomed to. However, some of the needs are the same. EVs will still require tires, headlights, taillights, turn signals, windshield wipers, and more. The Borgman Service Center is here to help you keep your vehicle running and driving at its best.

When Was The Last Time You Replaced Your Vehicle's Air Filters?

When was the last time you replaced your cabin air filter? In the spring, you’re likely inhaling more allergens, irritants, and pollutants. Your vehicle breathes too, and clogged filters mean it’s working harder than it needs to. Cabin Air Filters should be changed at least every 30,000 miles, but if you frequently drive in areas with a lot of pollution, you should change it sooner. The same goes for your engine air filter. If you have all of your regular maintenance done at Borgman, we keep track of these things and let you know when it's time. If you're just a tiny bit handy, both of these parts are easy enough to find and check. Cabin Air Filters are usually located behind your glove box, and the Engine Air Filter is right on top when you open the hood. Your manual will tell you exactly where they are, and what size you need. When you pull them out, most of the time it'll be pretty apparent if they need to be changed. However, if you're short on time or need help, Borgman is here to make sure you breathe easy this summer. What The Cabin Air Filter Does Your cabin air filter does exactly that - filters the air coming into your vehicle from outside. They're made of pleated material designed to trap incoming pollutants like dust, pollen, spores, and other particulates in the air and prevent them from entering the cabin when the heat or AC is on. When your filter starts to get clogged up with these pollutants, you might notice first that your vents don't blow as strong as they used to. Next, you might notice a musty smell, and then finally a whistling noise, as air is forced to find its way through gaps. Simply changing the filter will correct all of these issues at the source, but it may take some extra cleaning to get the musty smell out. If you're having trouble finding or replacing your cabin air filter, talk to the experts at Borgman - we'll have it replaced for you in no time. What The Engine Air Filter Does Just like how the Cabin Air Filter keeps airborne gunk out of your interior, the Engine Air Filter keeps the same things from getting inside your engine. These usually look like a bigger version of a Cabin Air Filter and are most commonly a cartridge style. However, some older or custom vehicles will have a drum style. Your engine needs three things to turn the wheels: fuel, spark, and fresh air. Just as your fuel filter removes any fine particulate, your air filter removes dirt, pollen, and other contaminants so they don't mix with fuel and coat your engine parts with carbon. If you don't have this filter changed, you'll notice your engine feeling sluggish and using more fuel to get moving. It makes sense when you think about it - try running a mile while holding your breath. Eventually, air will find its way in, carrying things the filter is supposed to be keeping out, and that means really expensive repairs. Borgman Service Center in Grand Rapids Helps You And Your Vehicle Breathe Easier If you're wondering when the last time your air filters were changed, give us a call at the Borgman Service Center. If you have us do all of your maintenance, we can check your file and let you know if you're overdue or not. If this is your first time with us, we'll take a look at both and make an honest recommendation. However, if you're in doubt, these are fairly inexpensive parts to replace.
