How can I make my CTS 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.

What’s making my CTS A/C put out warm 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 CTS's A/C system.

Does running the A/C in my CTS use gasoline?

CTS 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 CTS’s A/C smells like vinegar! What can cause that?

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 CTS creates a breeding environment for microorganisms.

Why won’t my CTS’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 CTS’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Service for Cadillac CTS

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like it's burning your hands. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Cadillac CTS A/C?” Easy — Firestone Complete Auto Care! We know our way around Cadillac vehicles, and our trained technicians can identify and repair issues with 2018 Cadillac A/C systems. Come to your local Firestone Complete Auto Care in your Cadillac CTS

During an A/C performance check, we'll determine the condition of your 2018 Cadillac CTS A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and 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 Cadillac CTS 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 Cadillac CTS

Let's say we repair your 2018 Cadillac CTS A/C system. We will also perform 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 Cadillac's recommendations. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 2018 Cadillac CTS A/C recharges.

Troubleshooting Cadillac CTS A/C Problems

Warm air isn't the only Cadillac CTS A/C problem you may encounter. 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 can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2018 Cadillac CTS? 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. Don’t sweat it — we’re here to help you chill out again in your CTS.
