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. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my GMC C3500 A/C?” Firestone Complete Auto Care — that’s who! We’ve got experience with GMC vehicles, and our technicians are qualified to diagnose and repair 1991 GMC C3500 A/C systems. Bring your GMC C3500 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1991 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 think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." 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 detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

A/C Recharge for GMC C3500

Let's say we repair your 1991 GMC C3500 A/C system. We will also perform 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 perform an evacuation (also known as a discharge) on the entire system per GMC guidelines. Finally, we’ll recharge the A/C system with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 1991 GMC C3500 A/C recharges.

Common GMC C3500 A/C Problems

You may think warm air is the only potential GMC C3500 A/C problem you’ll have, but you may notice other issues, too. 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. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 1991 GMC C3500? 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 trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your C3500.

1991 GMC C3500 A/C System FAQs

  • How can I make my C3500 air conditioner colder? For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.
  • Why is my C3500 A/C blowing hot air? An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.
  • What can cause an A/C system leak? Over the years, the rubber seals and gaskets in your C3500’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.
