How do I make my S4 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 S4 A/C?

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.

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 S4's A/C system.

Does running the A/C in my S4 use gasoline?

The air conditioning system in your S4 does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.

What can cause the A/C in my S4 to smell like vinegar?

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 S4 creates a breeding environment for microorganisms.

What is causing my S4’s A/C to only work when the car is in motion?

If your A/C only works when the vehicle is moving, there could be a problem with part of your S4’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

Audi S4 A/C Repair

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. That puddle in the driver’s seat? Sweat. Ugh. “Who can fix my Audi S4 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know Audi vehicles, and our trained technicians can identify and repair issues with 1994 Audi A/C systems. Bring your Audi S4 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1994 Audi S4’s A/C system to determine whether repair work is needed. This check will include an examination of system pressure, a visual inspection, and a 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 Audi S4 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for Audi S4

Let's say we repair your 1994 Audi S4 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 Audi's recommendations. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you're ready to get back on the road. Our technicians are trained to efficiently perform 1994 Audi S4 A/C recharges.

Other Audi S4 A/C Problems

You may think warm air is the only potential Audi S4 A/C problem you’ll have, but you may notice other issues, too. 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 may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 1994 Audi S4? 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. We’re here to help you get back on the road in your S4 — without all the sweat puddles!
