How do I make my Sonoma 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 is my Sonoma 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 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 Sonoma's A/C system.

Does my Sonoma A/C use gas?

Your Sonoma’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.

What can cause the A/C in my Sonoma to smell like vinegar?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your Sonoma creates a breeding environment for microorganisms.

What is causing my Sonoma’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 Sonoma may have a faulty cooling fan or low refrigerant.

A/C Repair Service for Your GMC Sonoma

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like lava. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC Sonoma?" Firestone Complete Auto Care can! We know GMC vehicles, and our qualified technicians can diagnose and service the A/C system in your 1991 GMC. Bring your GMC Sonoma to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1991 GMC Sonoma’s A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your GMC Sonoma A/C system to identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

Recharge the A/C in Your Sonoma

While your 1991 GMC Sonoma’s air conditioner is being serviced, we’ll also do 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). 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 all set. We want you to be comfortable in your car, so we train our technicians to perform 1991 GMC Sonoma A/C recharges.

Common GMC Sonoma A/C Problems

Warm air isn't the only GMC Sonoma A/C problem you may encounter. Another common A/C problem is 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 your A/C system blows cold air first but then it turns warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. And smelly A/C in a 1991 GMC Sonoma? 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 Sonoma.
