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. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC Terrain?" 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 2012 GMC. Come to your local Firestone Complete Auto Care in your GMC Terrain

During this initial A/C performance check, we’ll look at the state of your 2012 GMC Terrain’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. A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your GMC Terrain A/C system to detect any refrigerant fumes that might be leaking out from the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for GMC Terrain

Let's say we repair your 2012 GMC Terrain A/C system. We will also perform an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Next, they will evacuate the system according to GMC's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 2012 GMC Terrain A/C recharges.

Troubleshooting 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. Typical A/C problems also 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. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2012 GMC Terrain? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. So, chill out. We're here to help you get the blast back in your Terrain’s A/C!

2012 GMC Terrain A/C System FAQs

  • How can I make my Terrain 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 is my Terrain A/C blowing hot air? 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? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Terrain’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Does my Terrain A/C run on gas? Your Terrain’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 Terrain to smell like vinegar? If the air conditioning in your Terrain 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 Terrain’s A/C to only work when the car is in motion? 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.
