A/C Service for Mercedes-Benz GLS450

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. “Who can fix my Mercedes-Benz GLS450 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2018 Mercedes-Benz A/C systems. Steer your Mercedes-Benz GLS450 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2018 Mercedes-Benz GLS450 A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and leak test. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called 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 GLS450 A/C system to identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

Recharge the A/C in Your GLS450

When we perform an A/C repair on your 2018 Mercedes-Benz GLS450, 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). Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you're ready to get back on the road. Our technicians are trained to efficiently perform 2018 Mercedes-Benz GLS450 A/C recharges.

Common Mercedes-Benz GLS450 A/C Problems

Warm air isn't the only Mercedes-Benz GLS450 A/C problem you may encounter. Other common A/C problems include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. 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 2018 Mercedes-Benz GLS450? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. 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 GLS450 — without all the sweat puddles!

2018 Mercedes-Benz GLS450 A/C System FAQs

  • How do I make my GLS450 air conditioning 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.
  • Why do I get hot air from my GLS450 A/C? 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.
  • How does my A/C system get a leak? Over the years, the rubber seals and gaskets in your GLS450’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 my GLS450 A/C run on gas? GLS450 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 GLS450 smells like vinegar? If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your GLS450 creates a breeding environment for microorganisms.
  • Why does my vehicle have to be moving for my GLS450’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 GLS450’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.
