How can I make my A4 air conditioner colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

What’s making my A4 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 A4's A/C system.

Is my A4 A/C powered by gas?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your A4.

What does it mean if the A/C in my A4 smells 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 A4 to produce a vinegary odor.

Why won’t my A4’s A/C cool the vehicle when the car is stopped?

Damaged or worn components in your A4’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

A/C Service for Audi A4

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Audi A4?" Firestone Complete Auto Care can! We know our way around Audi vehicles, and our qualified technicians can diagnose and service the A/C system in your 1999 Audi. Bring your Audi A4 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1999 Audi A4’s A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a 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” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Audi A4 A/C system to detect any refrigerant fumes that might be leaking out from the system. If there's a leak, we'll find it and fix it.

A4 A/C Recharge

Let's say we repair your 1999 Audi A4 A/C system. We will also perform 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. 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. We want you to be comfortable in your car, so we train our technicians to perform 1999 Audi A4 A/C recharges.

Common Audi A4 A/C Problems

Hot air is a common Audi A4 A/C problem, but it’s not the only issue you might encounter. Typical A/C problems also include 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 be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 1999 Audi A4? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. So, chill out. We're here to help you get the blast back in your A4’s A/C!
