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?

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.

How does my A/C system get a 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 GLC300’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my GLC300 A/C run on 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?

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 GLC300 to have a vinegar-like smell.

Why does my GLC300’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 GLC300 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Service for Mercedes-Benz GLC300

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz GLC300 A/C?” Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2018 Mercedes-Benz. Steer your Mercedes-Benz GLC300 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2018 Mercedes-Benz GLC300’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 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 your system has a leak, we can get it fixed.

A/C Recharge for Mercedes-Benz GLC300

While your 2018 Mercedes-Benz GLC300’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 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 after one final test to be sure the system is cooling properly, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2018 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 mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. 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. And smelly A/C in a 2018 Mercedes-Benz GLC300? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your GLC300’s A/C!
