How can I make my 740i air conditioner 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.

What’s making my 740i A/C put out warm 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?

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 the A/C in my 740i rely on gas?

The air conditioning system in your 740i does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.

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.

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

If your A/C only works when the vehicle is moving, there could be a problem with part of your 740i’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

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 it's burning your hands. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my BMW 740i?" Firestone Complete Auto Care — that’s who! We know BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 2000 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 2000 BMW 740i A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and leak test. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different 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.

Recharge the A/C in Your 740i

While your 2000 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. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per BMW guidelines. Finally, we’ll recharge the A/C system with new refrigerant and once we’ve done a final test on the system ourselves, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 2000 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. Other common A/C problems include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 2000 BMW 740i? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. Don’t sweat it — we’re here to help you chill out again in your 740i.
