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?

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 740i's A/C system.

Does the A/C in my 740i use 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.

Why does the A/C in my 740i smell like vinegar?

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 740i creates a breeding environment for microorganisms.

What is causing my 740i’s A/C to only work when the car is in motion?

Damaged or worn components in your 740i’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

BMW 740i A/C Repair

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like it's burning your hands. Sweat soaks the driver's seat. 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 qualified technicians can diagnose and service the A/C system in your 1998 BMW. Come to your local Firestone Complete Auto Care in your BMW 740i

In this A/C performance inspection, we’ll check out the current condition of your 1998 BMW 740i A/C system to evaluate what repairs are necessary (if any). 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 740i A/C system to identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

740i A/C Recharge

While your 1998 BMW 740i’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per BMW guidelines. The A/C system is recharged with new refrigerant and once the technician tests the cool blast for themselves, you're ready to get back on the road. Our technicians are trained to efficiently perform 1998 BMW 740i A/C recharges.

Other BMW 740i A/C Problems

Hot air is a common BMW 740i A/C problem, but it’s not the only issue you might 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. If your A/C system blows cold air first but then it turns warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 1998 BMW 740i? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your 740i’s A/C!
