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.

What’s making my Terrain A/C put out warm 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.

How does my A/C system get a 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?

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.

Why does the A/C in my Terrain smell like vinegar?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your Terrain to produce a vinegary odor.

Why won’t my Terrain’s A/C cool the vehicle when the car is stopped?

If your A/C only works when the vehicle is moving, there could be a problem with part of your Terrain’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Repair Service for Your GMC Terrain

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. That puddle in the driver’s seat? Sweat. Ugh. “Who can fix my GMC Terrain A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We know GMC vehicles, and our technicians are qualified to diagnose and repair 2019 GMC Terrain A/C systems. 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 2019 GMC Terrain’s A/C system to determine whether repair work is needed. We’ll test overall system performance, check for any leaks, and measure the system pressure. 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" 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 there's a leak, we'll find it and fix it.

A/C Recharge for GMC Terrain

While your 2019 GMC Terrain’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll use GMC’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system, and after one final test to be sure the system is cooling properly, you’re all set. Our technicians know how to keep your A/C in tip-top shape with 2019 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. 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 suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 2019 GMC Terrain? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. We’re here to help you get back on the road in your Terrain — without all the sweat puddles!
