A/C Service for GMC S15

Few things are worse than a broken car air conditioner on a hot summer day. 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 S15 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 1990 GMC S15 A/C systems. Steer your GMC S15 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1990 GMC S15 A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. 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 S15 A/C system to detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your S15

While your 1990 GMC S15’s air conditioner is being serviced, 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. Next, they will evacuate the system according to GMC's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, and once we’ve done a final test on the system ourselves, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 1990 GMC S15 A/C recharges.

Common GMC S15 A/C Problems

Warm air isn't the only GMC S15 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 can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 1990 GMC S15? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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 S15.

1990 GMC S15 A/C System FAQs

  • Can I make my S15 air conditioner 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.
  • Why do I get hot air from my S15 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.
  • How does my A/C system get a leak? 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 S15's A/C system.
  •  Does running the A/C in my S15 use gasoline? While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your S15.
  • What does it mean if the A/C in my S15 smells like vinegar? Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your S15 to have a vinegar-like smell.
  • Why does my S15’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 S15 is moving. You may be low on refrigerant, or the cooling fan could be faulty.
