How do I make my 545i air conditioning 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 is my 545i A/C blowing hot 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.

What causes A/C system leaks?

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 545i's A/C system.

Does the A/C in my 545i use gas?

545i air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.

Why does the A/C in my 545i smell like vinegar?

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 545i to have a vinegar-like smell.

Why does my 545i’s A/C only work when the car is moving?

There could be issues with one or more components in the air conditioning or electrical system. Your 545i may have a faulty cooling fan or low refrigerant.

During this initial A/C performance check, we’ll look at the state of your 2005 BMW 545i’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 we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. A "sniffer" is a machine that's run along parts of your BMW 545i A/C system that can detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

Let's say we repair your 2005 BMW 545i A/C system. We will also perform an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll use BMW’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system, and once the technician tests the cool blast for themselves, you’re all set. Our technicians are trained to efficiently perform 2005 BMW 545i A/C recharges.

Other BMW 545i A/C Problems

Warm air isn't the only BMW 545i A/C problem you may encounter. Other common A/C problems 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. Are you breathing in some “interesting” new odors in your 2005 BMW 545i? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter.
