How can I make my S15 air conditioner 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 is my S15 A/C blowing hot 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 can cause an A/C system 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 my S15 A/C run on gas?

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.

My S15’s A/C smells like vinegar! What can cause that?

If the air conditioning in your S15 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.

What is causing my S15’s A/C to only work when the car is in motion?

There could be issues with one or more components in the air conditioning or electrical system. Your S15 may have a faulty cooling fan or low refrigerant.

A/C Repair Service for Your 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. “Who can fix my GMC S15 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We’ve got experience with GMC vehicles, and our technicians are qualified to diagnose and repair 1988 GMC S15 A/C systems. Come to your local Firestone Complete Auto Care in your GMC S15

In this A/C performance inspection, we’ll check out the current condition of your 1988 GMC S15 A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a 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." A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different 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.

A/C Recharge for GMC S15

Let's say we repair your 1988 GMC S15 A/C system. We will also perform an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Then, they’ll use GMC’s specifications to evacuate the system. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. Our technicians are trained to efficiently perform 1988 GMC S15 A/C recharges.

Troubleshooting GMC S15 A/C Problems

Warm air isn't the only GMC S15 A/C problem you may encounter. 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. An A/C system that starts off blowing cold air but then turns warm may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. And smelly A/C in a 1988 GMC S15? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. 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 S15.
