How do I make my Terrain 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 Terrain A/C?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

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 Terrain's A/C system.

Does my Terrain A/C run on gas?

Terrain 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.

Why does the A/C in my Terrain 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 Terrain creates a breeding environment for microorganisms.

Why does my Terrain’s A/C only work when the car is moving?

Damaged or worn components in your Terrain’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.

GMC Terrain 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. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my GMC Terrain A/C?” Firestone Complete Auto Care can! We’ve got experience with GMC vehicles, and our technicians are qualified to diagnose and repair 2013 GMC Terrain A/C systems. Steer your GMC Terrain to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2013 GMC Terrain’s A/C system to evaluate what repairs are necessary (if any). 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 Terrain 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.

Terrain A/C Recharge

When we perform an A/C repair on your 2013 GMC Terrain, 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). 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 all set. We want you to be comfortable in your car, so we train our technicians to perform 2013 GMC Terrain A/C recharges.

Troubleshooting GMC Terrain A/C Problems

You may think warm air is the only potential GMC Terrain A/C problem you’ll have, but you may notice other issues, too. 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 may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 2013 GMC Terrain? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our technicians will work to solve your A/C problems to the best of their ability. Don’t sweat it — we’re here to help you chill out again in your Terrain.
