How can I make my GLC300 air conditioner 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 GLC300 A/C?

If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

What causes A/C system leaks?

Over the years, the rubber seals and gaskets in your GLC300’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.

Is my GLC300 A/C powered by gas?

The air conditioning system in your GLC300 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.

My GLC300’s A/C smells like vinegar! What can cause that?

If the air conditioning in your GLC300 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 won’t my GLC300’s A/C cool the vehicle when the car is stopped?

A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your GLC300 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

Mercedes-Benz GLC300 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like lava. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz GLC300?" Firestone Complete Auto Care — that’s who! We know Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2021 Mercedes-Benz A/C systems. Bring your Mercedes-Benz GLC300 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2021 Mercedes-Benz GLC300’s A/C system to determine whether repair work is needed. 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.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz GLC300 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.

GLC300 A/C Recharge

While your 2021 Mercedes-Benz GLC300’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. 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. We want you to be comfortable in your car, so we train our technicians to perform 2021 Mercedes-Benz GLC300 A/C recharges.

Other Mercedes-Benz GLC300 A/C Problems

Warm air isn't the only Mercedes-Benz GLC300 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 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 2021 Mercedes-Benz GLC300? 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. Don’t sweat it — we’re here to help you chill out again in your GLC300.
