How do I make my GL450 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.

What’s making my GL450 A/C put out warm air?

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?

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 GL450's A/C system.

Does running the A/C in my GL450 use gasoline?

The air conditioning system in your GL450 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 the A/C in my GL450 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 GL450 to have a vinegar-like smell.

Why does my vehicle have to be moving for my GL450’s A/C to work?

Damaged or worn components in your GL450’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

Mercedes-Benz GL450 A/C Repair

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 wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz GL450?" Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2013 Mercedes-Benz A/C systems. Steer your Mercedes-Benz GL450 to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2013 Mercedes-Benz GL450 A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure. 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” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Mercedes-Benz GL450 A/C system to 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.

A/C Recharge for Mercedes-Benz GL450

When we perform an A/C repair on your 2013 Mercedes-Benz GL450, 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 once we’ve done a final test on the system ourselves, you're ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 2013 Mercedes-Benz GL450 A/C recharges.

Other Mercedes-Benz GL450 A/C Problems

You may think warm air is the only potential Mercedes-Benz GL450 A/C problem you’ll have, but you may notice other issues, too. 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. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 2013 Mercedes-Benz GL450? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. 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 GL450’s A/C!
