A/C Service for BMW 740i

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. 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 know our way around BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 1999 BMW. Steer your BMW 740i to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1999 BMW 740i’s A/C system to see if repair work is required. 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 detect any refrigerant fumes that might be leaking out from the system. If your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your 740i

When we perform an A/C repair on your 1999 BMW 740i, we’ll also do an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). 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 the technician tests the cool blast for themselves, you’re good to go. Our technicians know how to keep your A/C in tip-top shape with 1999 BMW 740i A/C recharges.

Troubleshooting BMW 740i A/C Problems

Warm air isn't the only BMW 740i A/C problem you may encounter. Another common A/C problem is weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If your A/C system blows cold air first but then it turns warm, this 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 1999 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.

Questions About 1999 BMW 740i A/C Systems

  • 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.
  • 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.
  • What causes A/C system leaks? 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 rely on gas? 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 does it mean if the A/C in my 740i smells like vinegar? If the air conditioning in your 740i 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.
  • What is causing my 740i’s A/C to only work when the car is in motion? 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.
  • Where can I get my 740i’s A/C repaired? Firestone Complete Auto Care has decades of experience inspecting and repairing 740i air conditioning systems. Schedule an A/C repair appointment at one of our locations near you today.
