GMC G3500 A/C Repair

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. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my GMC G3500 A/C?” Easy — Firestone Complete Auto Care! We know our way around GMC vehicles, and our trained technicians can identify and repair issues with 1990 GMC A/C systems. Steer your GMC G3500 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1990 GMC G3500’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 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 G3500 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for GMC G3500

When we perform an A/C repair on your 1990 GMC G3500, 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 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 know how to keep your A/C in tip-top shape with 1990 GMC G3500 A/C recharges.

Common GMC G3500 A/C Problems

You may think warm air is the only potential GMC G3500 A/C problem you’ll have, but you may notice other issues, too. Other common A/C problems include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 1990 GMC G3500? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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 G3500.

Frequently Asked Questions for 1990 GMC G3500 A/C Systems

  • How do I make my G3500 air conditioning 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.
  • Why do I get hot air from my G3500 A/C? If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.
  • 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 G3500’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
