A/C Service for GMC Terrain

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my GMC Terrain A/C?” Firestone Complete Auto Care can! We know our way around GMC vehicles, and our qualified technicians can diagnose and service the A/C system in your 2018 GMC. Bring your GMC Terrain to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2018 GMC Terrain’s A/C system to determine whether repair work is needed. This check will include an examination of system pressure, a visual inspection, and a leak test. 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" is a machine that's run along parts of your GMC Terrain A/C system that can identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for GMC Terrain

When we perform an A/C repair on your 2018 GMC Terrain, 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 all set. Our technicians are trained to efficiently perform 2018 GMC Terrain A/C recharges.

Other GMC Terrain A/C Problems

Hot air is a common GMC Terrain A/C problem, but it’s not the only issue you might encounter. Other common A/C problems include 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. Are you breathing in some “interesting” new odors in your 2018 GMC Terrain? 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 technicians will work to solve your A/C problems to the best of their ability. We’re here to help you get back on the road in your Terrain — without all the sweat puddles!

2018 GMC Terrain A/C System FAQs

  • Can I make my Terrain 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 Terrain A/C blowing hot air? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • 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 Terrain's A/C system.
  •  Does the A/C in my Terrain use 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.
  • My Terrain’s A/C smells like vinegar! What can cause that? 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 Terrain to have a vinegar-like smell.
  • Why does my vehicle have to be moving for my Terrain’s A/C to work? There could be issues with one or more components in the air conditioning or electrical system. Your Terrain may have a faulty cooling fan or low refrigerant.
