How can I make my F-150 air conditioner colder?

Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.

What’s making my F-150 A/C put out warm air?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

What causes A/C system leaks?

To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your F-150’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does the A/C in my F-150 use gas?

Your F-150’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

What can cause the A/C in my F-150 to smell like vinegar?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your F-150 to produce a vinegary odor.

Why does my F-150’s A/C only work when the car is moving?

Damaged or worn components in your F-150’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

A/C Service for Ford F-150

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. “Who can fix my Ford F-150 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We’ve got experience with Ford vehicles, and our qualified technicians can diagnose and service the A/C system in your 1991 Ford. Steer your Ford F-150 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1991 Ford F-150’s A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Ford F-150 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

Recharge the A/C in Your F-150

While your 1991 Ford F-150’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll use Ford’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system, and once we’ve done a final test on the system ourselves, you’re good to go. Our technicians know how to keep your A/C in tip-top shape with 1991 Ford F-150 A/C recharges.

Other Ford F-150 A/C Problems

Hot air is a common Ford F-150 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 1991 Ford F-150? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Our technicians will work to solve your A/C problems to the best of their ability. So, chill out. We're here to help you get the blast back in your F-150’s A/C!
