Can I make my ML550 air conditioner 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.

Why is my ML550 A/C blowing hot air?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

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 ML550’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Is my ML550 A/C powered by gas?

The air conditioning system in your ML550 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 does it mean if the A/C in my ML550 smells like vinegar?

If the air conditioning in your ML550 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 ML550’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 ML550 may have a faulty cooling fan or low refrigerant.

A/C Service for Mercedes-Benz ML550

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. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz ML550 A/C?” Firestone Complete Auto Care can! We’ve got experience with Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2012 Mercedes-Benz. Steer your Mercedes-Benz ML550 to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2012 Mercedes-Benz ML550 A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a leak test. If we think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Mercedes-Benz ML550 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.

ML550 A/C Recharge

While your 2012 Mercedes-Benz ML550’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. Next, they will evacuate the system according to Mercedes-Benz'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 good to go. We want you to be comfortable in your car, so we train our technicians to perform 2012 Mercedes-Benz ML550 A/C recharges.

Common Mercedes-Benz ML550 A/C Problems

Hot air is a common Mercedes-Benz ML550 A/C problem, but it’s not the only issue you might 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 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 2012 Mercedes-Benz ML550? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. We’re here to help you get back on the road in your ML550 — without all the sweat puddles!
