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. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz GLS450 A/C?” Easy — Firestone Complete Auto Care! We’ve got experience with Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2023 Mercedes-Benz 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 2023 Mercedes-Benz GLS450 A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. 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" 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 A/C system has a leak, we’ll find and repair it.

GLS450 A/C Recharge

While your 2023 Mercedes-Benz GLS450’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. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you're ready to get back on the road. Our technicians are trained to efficiently perform 2023 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. Another common A/C problem is 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 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 2023 Mercedes-Benz GLS450? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. Don’t sweat it — we’re here to help you chill out again in your GLS450.

Questions About 2023 Mercedes-Benz GLS450 A/C Systems

  • Can I make my GLS450 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 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.
  • What causes A/C system leaks? A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your GLS450's A/C system.
  • Does my GLS450 A/C use gas?  The air conditioning system in your GLS450 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.
  • Why does my GLS450 have a vinegary smell coming from the A/C? 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? 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.
