How do I make my M5 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.

What’s making my M5 A/C put out warm air?

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.

What causes A/C system leaks?

Over the years, the rubber seals and gaskets in your M5’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 M5 use gasoline?

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 M5.

Why does my M5 have a vinegary smell coming from the A/C?

If the air conditioning in your M5 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 M5’s A/C only work when the car is moving?

A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your M5 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Service for BMW M5

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like it's burning your hands. That puddle in the driver’s seat? Sweat. Ugh. You wipe your brow and wonder, "Who can fix the A/C in my BMW M5?" Easy — Firestone Complete Auto Care! We know BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 1988 BMW. Steer your BMW M5 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1988 BMW M5 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 think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your BMW M5 A/C system to identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

A/C Recharge for BMW M5

While your 1988 BMW M5’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per BMW guidelines. The A/C system is recharged with new refrigerant 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 1988 BMW M5 A/C recharges.

Troubleshooting BMW M5 A/C Problems

Hot air is a common BMW M5 A/C problem, but it’s not the only issue you might encounter. Other common A/C problems 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 1988 BMW M5? 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. Don’t sweat it — we’re here to help you chill out again in your M5.
