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 do I get hot air from my 740i A/C?

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 causes A/C system leaks?

Over the years, the rubber seals and gaskets in your 740i’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.

Does running the A/C in my 740i use gasoline?

740i 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.

What can cause the A/C in my 740i to smell like vinegar?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your 740i to produce a vinegary odor.

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

BMW 740i 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. You take a deep breath and ask yourself, “Who can fix my BMW 740i A/C?” Firestone Complete Auto Care can! We’ve got experience with BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 2012 BMW. Bring your BMW 740i to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2012 BMW 740i A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. 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 740i A/C system to detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

740i A/C Recharge

When we perform an A/C repair on your 2012 BMW 740i, 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. 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 once the technician tests the cool blast for themselves, you’re good to go. Our technicians are trained to efficiently perform 2012 BMW 740i A/C recharges.

Common BMW 740i A/C Problems

You may think warm air is the only potential BMW 740i A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include 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 may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 2012 BMW 740i? 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. We’re here to help you get back on the road in your 740i — without all the sweat puddles!
