How do I make my GL450 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 GL450 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.

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 my GL450 A/C use gas?

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 GL450.

What can cause the A/C in my GL450 to smell like vinegar?

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 GL450 creates a breeding environment for microorganisms.

Why won’t my GL450’s A/C cool the vehicle when the car is stopped?

There could be issues with one or more components in the air conditioning or electrical system. Your GL450 may have a faulty cooling fan or low refrigerant.

Mercedes-Benz GL450 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. “Who can fix my Mercedes-Benz GL450 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2008 Mercedes-Benz A/C systems. Bring your Mercedes-Benz GL450 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2008 Mercedes-Benz GL450’s A/C system to determine whether repair work is needed. This check will include an examination of system pressure, a visual inspection, and a 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 GL450 A/C system that can detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

GL450 A/C Recharge

When we perform an A/C repair on your 2008 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). Next, they will evacuate the system according to Mercedes-Benz's recommendations. 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 all set. Our technicians know how to keep your A/C in tip-top shape with 2008 Mercedes-Benz GL450 A/C recharges.

Common Mercedes-Benz GL450 A/C Problems

Hot air is a common Mercedes-Benz GL450 A/C problem, but it’s not the only issue you might 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. An A/C system that starts off blowing cold air but then turns warm can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. Are you breathing in some “interesting” new odors in your 2008 Mercedes-Benz GL450? 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 GL450.
