How can I make my C3500 air conditioner colder?

Here are a few quick ideas. Shut the passenger air vents and point the other vents directly toward you. Park your car in the shade and use a window sun blocker. Then visit Firestone Complete Auto Care for an A/C performance check and recharge.

What’s making my C3500 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?

A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your C3500's A/C system.

Does the A/C in my C3500 use gas?

The air conditioning system in your C3500 does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.

My C3500’s A/C smells like vinegar! What can cause that?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your C3500 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my C3500’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your C3500 may have a faulty cooling fan or low refrigerant.

A/C Service for GMC C3500

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Is that a hot stove? Nope, just your steering wheel. That puddle in the driver’s seat? Sweat. Ugh. “Who can fix my GMC C3500 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know GMC vehicles, and our qualified technicians can diagnose and service the A/C system in your 1998 GMC. Steer your GMC C3500 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1998 GMC C3500 A/C system to determine whether repair work is needed. This check will include an examination of system pressure, a visual inspection, and a leak test. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your GMC C3500 A/C system to identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for GMC C3500

When we perform an A/C repair on your 1998 GMC C3500, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll use GMC’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 all set. Our technicians know how to keep your A/C in tip-top shape with 1998 GMC C3500 A/C recharges.

Other GMC C3500 A/C Problems

Hot air is a common GMC C3500 A/C problem, but it’s not the only issue you might encounter. Typical A/C problems also include 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 be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. And smelly A/C in a 1998 GMC C3500? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. So, chill out. We're here to help you get the blast back in your C3500’s A/C!
