A/C Repair Service for Your GMC R1500 Suburban

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like it's burning your hands. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC R1500 Suburban?" Easy — Firestone Complete Auto Care! We’ve got experience with GMC vehicles, and our qualified technicians can diagnose and service the A/C system in your 1990 GMC. Come to your local Firestone Complete Auto Care in your GMC R1500 Suburban

During this initial A/C performance check, we’ll look at the state of your 1990 GMC R1500 Suburban’s A/C system to determine whether repair work is needed. We’ll test overall system performance, check for any leaks, and measure the system pressure. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your GMC R1500 Suburban 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.

Recharge the A/C in Your R1500 Suburban

While your 1990 GMC R1500 Suburban’s air conditioner is being serviced, 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. The A/C system is recharged with new refrigerant 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 1990 GMC R1500 Suburban A/C recharges.

Common GMC R1500 Suburban A/C Problems

Hot air is a common GMC R1500 Suburban A/C problem, but it’s not the only issue you might 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 your A/C system blows cold air first but then it turns warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 1990 GMC R1500 Suburban? 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. So, chill out. We're here to help you get the blast back in your R1500 Suburban’s A/C!

Questions About 1990 GMC R1500 Suburban A/C Systems

  • How do I make my R1500 Suburban air conditioning colder? Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.
  • What’s making my R1500 Suburban A/C put out warm air? 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? 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 R1500 Suburban's A/C system.
  •  Does running the A/C in my R1500 Suburban use gasoline? Your R1500 Suburban’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.
  • My R1500 Suburban’s A/C smells like vinegar! What can cause that? It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your R1500 Suburban to produce a vinegary odor.
  • Why does my R1500 Suburban’s A/C only work when the car is moving? Damaged or worn components in your R1500 Suburban’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.
  • Where can I get my R1500 Suburban’s A/C repaired? When you need your R1500 Suburban air conditioning system repaired or inspected, trust Firestone Complete Auto Care. Schedule an appointment at our A/C repair shop near you.
