How can I make my 745Li air conditioner 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.

Why is my 745Li 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 can cause an A/C system leak?

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 745Li’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does running the A/C in my 745Li use gasoline?

745Li 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.

My 745Li’s A/C smells like vinegar! What can cause that?

If the air conditioning in your 745Li 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 745Li’s A/C only work when the car is moving?

If your A/C only works when the vehicle is moving, there could be a problem with part of your 745Li’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Service for BMW 745Li

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 745Li?" Firestone Complete Auto Care can! We know our way around BMW vehicles, and our technicians are qualified to diagnose and repair 2005 BMW 745Li A/C systems. Steer your BMW 745Li to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2005 BMW 745Li’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. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your BMW 745Li 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 745Li

Let's say we repair your 2005 BMW 745Li A/C system. We will also perform 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. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per BMW guidelines. 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 good to go. We want you to be comfortable in your car, so we train our technicians to perform 2005 BMW 745Li A/C recharges.

Common BMW 745Li A/C Problems

You may think warm air is the only potential BMW 745Li A/C problem you’ll have, but you may notice other issues, too. 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. Are you breathing in some “interesting” new odors in your 2005 BMW 745Li? 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. We’re here to help you get back on the road in your 745Li — without all the sweat puddles!
