How do I make my 645Ci 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 do I get hot air from my 645Ci 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 645Ci's A/C system.

Does running the A/C in my 645Ci 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 645Ci.

Why does my 645Ci have a vinegary smell coming from the A/C?

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 645Ci creates a breeding environment for microorganisms.

Why does my 645Ci’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 645Ci is moving. You may be low on refrigerant, or the cooling fan could be faulty.

You take a deep breath and ask yourself, “Who can fix my BMW 645Ci A/C?” Easy — Firestone Complete Auto Care! We know our way around BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 2005 BMW. Steer your BMW 645Ci to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2005 BMW 645Ci 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 645Ci A/C system that can detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for BMW 645Ci

When we perform an A/C repair on your 2005 BMW 645Ci, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. 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. Our technicians are trained to efficiently perform 2005 BMW 645Ci A/C recharges.

Other BMW 645Ci A/C Problems

Hot air is a common BMW 645Ci A/C problem, but it’s not the only issue you might 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. An A/C system that starts off blowing cold air but then turns warm can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2005 BMW 645Ci? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. 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 645Ci’s A/C!
