When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my GMC C3500 A/C?” Easy — Firestone Complete Auto Care! We know GMC vehicles, and our qualified technicians can diagnose and service the A/C system in your 1990 GMC. Bring your GMC C3500 to your local Firestone Complete Auto Care
During this initial A/C performance check, we’ll look at the state of your 1990 GMC C3500’s A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and 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. A "sniffer" is a machine that's run along parts of your GMC C3500 A/C system that can detect any refrigerant fumes that might be leaking out from the system. If there's a leak, we'll find it and fix it.
Let's say we repair your 1990 GMC C3500 A/C system. We will also perform an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per GMC guidelines. The A/C system is recharged 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 1990 GMC C3500 A/C recharges.
Warm air isn't the only GMC C3500 A/C problem you may encounter. Another common A/C problem is weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 1990 GMC C3500? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your C3500.
