How do I make my 640i air conditioning colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

What’s making my 640i 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 640i’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 640i use gasoline?

The air conditioning system in your 640i 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.

Why does the A/C in my 640i smell like vinegar?

If the air conditioning in your 640i smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.

Why does my vehicle have to be moving for my 640i’s A/C to work?

If your A/C only works when the vehicle is moving, there could be a problem with part of your 640i’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Service for BMW 640i

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 640i A/C?” Firestone Complete Auto Care can! We’ve got experience with BMW vehicles, and our trained technicians can identify and repair issues with 2015 BMW A/C systems. Steer your BMW 640i to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2015 BMW 640i 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. A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your BMW 640i 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 640i

While your 2015 BMW 640i’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 use BMW’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system, and after one final test to be sure the system is cooling properly, 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 2015 BMW 640i A/C recharges.

Common BMW 640i A/C Problems

Hot air is a common BMW 640i A/C problem, but it’s not the only issue you might encounter. Other common A/C problems 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 can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2015 BMW 640i? 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. So, chill out. We're here to help you get the blast back in your 640i’s A/C!
