How do I make my ML400 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.

Why is my ML400 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 can cause an A/C system leak?

Over the years, the rubber seals and gaskets in your ML400’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 running the A/C in my ML400 use gasoline?

ML400 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 can cause the A/C in my ML400 to smell like vinegar?

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 ML400 to have a vinegar-like smell.

Why does my ML400’s A/C only work when the car is moving?

Damaged or worn components in your ML400’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

A/C Repair Service for Your Mercedes-Benz ML400

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz ML400?" Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2015 Mercedes-Benz. Steer your Mercedes-Benz ML400 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2015 Mercedes-Benz ML400 A/C system to determine whether repair work is needed. 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. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz ML400 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for Mercedes-Benz ML400

While your 2015 Mercedes-Benz ML400’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. Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you’re good to go. Our technicians are trained to efficiently perform 2015 Mercedes-Benz ML400 A/C recharges.

Troubleshooting Mercedes-Benz ML400 A/C Problems

You may think warm air is the only potential Mercedes-Benz ML400 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2015 Mercedes-Benz ML400? 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 ML400 — without all the sweat puddles!
