How can I make my GL450 air conditioner 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?

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 GL450’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

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 does it mean if the A/C in my GL450 smells like vinegar?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your GL450 to produce a vinegary odor.

Why won’t my GL450’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 GL450 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Service for Mercedes-Benz GL450

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. 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?" Firestone Complete Auto Care — that’s who! We know our way around Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2012 Mercedes-Benz GL450 A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz GL450

During an A/C performance check, we'll determine the condition of your 2012 Mercedes-Benz GL450 A/C system to determine whether repair work is needed. 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.” 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.

Recharge the A/C in Your GL450

While your 2012 Mercedes-Benz GL450’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). Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 2012 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. Typical A/C problems also 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 your A/C system blows cold air first but then it turns warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2012 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. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your GL450 — without all the sweat puddles!
