How do I make my GLS450 air conditioning colder?

Here are a few quick ideas. Shut the passenger air vents and point the other vents directly toward you. Park your car in the shade and use a window sun blocker. Then visit 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 can cause an A/C system leak?

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?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your GLS450.

Why does my GLS450 have a vinegary smell coming from the A/C?

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 vehicle have to be moving for my GLS450’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your GLS450 may have a faulty cooling fan or low refrigerant.

Mercedes-Benz GLS450 A/C Repair

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. That puddle in the driver’s seat? Sweat. Ugh.

We know our way around Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2024 Mercedes-Benz GLS450 A/C systems. Steer your Mercedes-Benz GLS450 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2024 Mercedes-Benz GLS450’s A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and leak test. 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. A "sniffer" is a machine that's run along parts of your Mercedes-Benz GLS450 A/C system that can identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

GLS450 A/C Recharge

When we perform an A/C repair on your 2024 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 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 ready to get back on the road. Our technicians are trained to efficiently perform 2024 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 indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2024 Mercedes-Benz GLS450? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. So, chill out. We're here to help you get the blast back in your GLS450’s A/C!
