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.
  •  Does the A/C in my G3500 use gas? G3500 air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.
  • My G3500’s A/C smells like vinegar! What can cause that? If the air conditioning in your G3500 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.
  • Why does my G3500’s A/C only work when the car is moving? A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your G3500 is moving. You may be low on refrigerant, or the cooling fan could be faulty.
