BMW 540i A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like lava. Your skin sticks to the driver’s seat. “Who can fix my BMW 540i A/C?” you wonder, as the sun beats through the windshield. 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 1999 BMW. Steer your BMW 540i to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1999 BMW 540i’s 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 we think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A "sniffer" is a machine that's run along parts of your BMW 540i A/C system that can identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for BMW 540i

Let's say we repair your 1999 BMW 540i A/C system. We will also perform 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). Next, they will evacuate the system according to BMW'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 good to go. We want you to be comfortable in your car, so we train our technicians to perform 1999 BMW 540i A/C recharges.

Other BMW 540i A/C Problems

Warm air isn't the only BMW 540i A/C problem you may 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. And smelly A/C in a 1999 BMW 540i? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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 540i’s A/C!

Frequently Asked Questions for 1999 BMW 540i A/C Systems

  • Can I make my 540i 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.
  • Why do I get hot air from my 540i 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.
  • 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 540i’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Does my 540i 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 540i.
  • Why does my 540i have a vinegary smell coming from the A/C? Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your 540i to have a vinegar-like smell.
  • What is causing my 540i’s A/C to only work when the car is in motion? Damaged or worn components in your 540i’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.
