A/C Repair Service for Your Mercedes-Benz GLS450

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. Sweat soaks the driver's seat. “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’ve got experience with Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2019 Mercedes-Benz GLS450 A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz GLS450

In this A/C performance inspection, we’ll check out the current condition of your 2019 Mercedes-Benz GLS450 A/C system to evaluate what repairs are necessary (if any). 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" is a machine that's run along parts of your Mercedes-Benz GLS450 A/C system that can 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

While your 2019 Mercedes-Benz GLS450’s air conditioner is being serviced, 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 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 all set. Our technicians know how to keep your A/C in tip-top shape with 2019 Mercedes-Benz GLS450 A/C recharges.

Troubleshooting 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 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. And smelly A/C in a 2019 Mercedes-Benz GLS450? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Our trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your GLS450.

2019 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? 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? 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 my GLS450 A/C use 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.
  • Why does the A/C in my GLS450 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 GLS450 to have a vinegar-like smell.
  • 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.
