How do I make my STS 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.

Why do I get hot air from my STS A/C?

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 can cause an A/C system leak?

Over the years, the rubber seals and gaskets in your STS’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 STS use gasoline?

Your STS’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.

My STS’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 STS creates a breeding environment for microorganisms.

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

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

A/C Service for Cadillac STS

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. You wipe your brow and wonder, "Who can fix the A/C in my Cadillac STS?" Firestone Complete Auto Care can! We know our way around Cadillac vehicles, and our trained technicians can identify and repair issues with 2008 Cadillac A/C systems. Bring your Cadillac STS to your local Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2008 Cadillac STS 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 Cadillac STS 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.

STS A/C Recharge

When we perform an A/C repair on your 2008 Cadillac STS, 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. Then, they’ll use Cadillac’s specifications to evacuate the system. 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 good to go. We want you to be comfortable in your car, so we train our technicians to perform 2008 Cadillac STS A/C recharges.

Other Cadillac STS A/C Problems

Hot air is a common Cadillac STS A/C problem, but it’s not the only issue you might encounter. Typical A/C problems also include weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. 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. And smelly A/C in a 2008 Cadillac STS? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your STS.
