How do I make my CT4 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 CT4 A/C put out warm 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 causes A/C system leaks?

Over the years, the rubber seals and gaskets in your CT4’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.

Does running the A/C in my CT4 use gasoline?

CT4 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 CT4’s A/C smells like vinegar! What can cause that?

If the air conditioning in your CT4 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 CT4’s A/C to only work when the car is in motion?

A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your CT4 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Service for Cadillac CT4

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. Sweat soaks the driver's seat. “Who can fix my Cadillac CT4 A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We’ve got experience with Cadillac vehicles, and our qualified technicians can diagnose and service the A/C system in your 2021 Cadillac. Bring your Cadillac CT4 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2021 Cadillac CT4 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 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 CT4 A/C system that can detect any refrigerant fumes that might be leaking out from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for Cadillac CT4

Let's say we repair your 2021 Cadillac CT4 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). Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Cadillac guidelines. The A/C system is recharged with new refrigerant and once the technician tests the cool blast for themselves, you're ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 2021 Cadillac CT4 A/C recharges.

Other Cadillac CT4 A/C Problems

Warm air isn't the only Cadillac CT4 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 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2021 Cadillac CT4? 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. Don’t sweat it — we’re here to help you chill out again in your CT4.
