How can I make my M5 air conditioner 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 is my M5 A/C blowing hot 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?

To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your M5’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my M5 A/C use 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 M5.

What can cause the A/C in my M5 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 M5 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my M5’s A/C to work?

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. Is that a hot stove? Nope, just your steering wheel. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my BMW M5?" Firestone Complete Auto Care can! We’ve got experience with BMW vehicles, and our trained technicians can identify and repair issues with 1991 BMW A/C systems. Steer your BMW M5 to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 1991 BMW M5 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 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" is a machine that's run along parts of your BMW M5 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.

M5 A/C Recharge

When we perform an A/C repair on your 1991 BMW M5, 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. Next, they will evacuate the system according to BMW's recommendations. 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 ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 1991 BMW M5 A/C recharges.

Other BMW M5 A/C Problems

Warm air isn't the only BMW M5 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 your A/C system blows cold air first but then it turns warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 1991 BMW M5? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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 M5.
