How do I make my M3 air conditioning colder?

Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.

Why do I get hot air from my M3 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.

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 M3's A/C system.

Does the A/C in my M3 use gas?

Your M3’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.

What does it mean if the A/C in my M3 smells like vinegar?

If the air conditioning in your M3 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.

Why does my M3’s A/C only work when the car is moving?

Damaged or worn components in your M3’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 Repair Service for Your BMW M3

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my BMW M3 A/C?” Firestone Complete Auto Care — that’s who! We know BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 1989 BMW. Come to your local Firestone Complete Auto Care in your BMW M3

In this A/C performance inspection, we’ll check out the current condition of your 1989 BMW M3 A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure. 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 BMW M3 A/C system to detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

M3 A/C Recharge

While your 1989 BMW M3’s air conditioner is being serviced, we’ll also do 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 BMW guidelines. To finish, we’ll add new refrigerant to recharge the A/C system, and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 1989 BMW M3 A/C recharges.

Troubleshooting BMW M3 A/C Problems

Warm air isn't the only BMW M3 A/C problem you may encounter. Typical A/C problems also include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 1989 BMW M3? 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 trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your M3 — without all the sweat puddles!
