Mercedes-Benz GLS450 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. 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 GLS450?" Firestone Complete Auto Care can! We know our way around Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2021 Mercedes-Benz. Come to your local Firestone Complete Auto Care in your Mercedes-Benz GLS450

During an A/C performance check, we'll determine the condition of your 2021 Mercedes-Benz GLS450 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 any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz GLS450 A/C system to detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your GLS450

Let's say we repair your 2021 Mercedes-Benz GLS450 A/C system. We will also perform 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 use Mercedes-Benz’s specifications to evacuate the system. 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. Our technicians know how to keep your A/C in tip-top shape with 2021 Mercedes-Benz GLS450 A/C recharges.

Other 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. 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. And smelly A/C in a 2021 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!

2021 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.
  • What’s making my GLS450 A/C put out warm 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 GLS450’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 GLS450 use gasoline? 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.
  • Why does the A/C in my GLS450 smell like vinegar? If the air conditioning in your GLS450 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 GLS450’s A/C only work when the car is moving? A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your GLS450 is moving. You may be low on refrigerant, or the cooling fan could be faulty.
