How do I make my 740i air conditioning 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 740i 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 can cause an A/C system 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 740i's A/C system.

Does the A/C in my 740i rely on 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 740i.

My 740i’s A/C smells like vinegar! What can cause that?

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 740i to have a vinegar-like smell.

Why does my vehicle have to be moving for my 740i’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 740i is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Repair Service for Your BMW 740i

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my BMW 740i A/C?” Easy — Firestone Complete Auto Care! We’ve got experience with BMW vehicles, and our technicians are qualified to diagnose and repair 2015 BMW 740i A/C systems. Steer your BMW 740i to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2015 BMW 740i A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. 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 740i A/C system that can detect any refrigerant fumes that might be leaking out from the system. If your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your 740i

While your 2015 BMW 740i’s air conditioner is being serviced, 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 ready to get back on the road. Our technicians are trained to efficiently perform 2015 BMW 740i A/C recharges.

Other BMW 740i A/C Problems

Warm air isn't the only BMW 740i A/C problem you may encounter. Another common A/C problem is weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. 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. And smelly A/C in a 2015 BMW 740i? 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 740i.
