Can I make my 740i 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.

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 causes A/C system leaks?

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 740i’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 740i use gasoline?

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 my 740i have a vinegary smell coming from the A/C?

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 740i’s A/C only work when the car is moving?

There could be issues with one or more components in the air conditioning or electrical system. Your 740i may have a faulty cooling fan or low refrigerant.

A/C Repair Service for Your BMW 740i

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. 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?” 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 2017 BMW. Steer your BMW 740i to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2017 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 suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. 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 your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your 740i

Let's say we repair your 2017 BMW 740i 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. Next, they will evacuate the system according to BMW's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, and once we’ve done a final test on the system ourselves, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2017 BMW 740i A/C recharges.

Troubleshooting 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. 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. 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 2017 BMW 740i? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our technicians will work to solve your A/C problems to the best of their ability. We’re here to help you get back on the road in your 740i — without all the sweat puddles!
