How do I make my GL350 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.

Why is my GL350 A/C blowing hot 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.

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 GL350’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Is my GL350 A/C powered by gas?

Your GL350’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

What can cause the A/C in my GL350 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 GL350 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my GL350’s A/C to work?

Damaged or worn components in your GL350’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.

A/C Repair Service for Your Mercedes-Benz GL350

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. “Who can fix my Mercedes-Benz GL350 A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We know Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2012 Mercedes-Benz A/C systems. Steer your Mercedes-Benz GL350 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2012 Mercedes-Benz GL350 A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. 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" is a machine that's run along parts of your Mercedes-Benz GL350 A/C system that can 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 GL350

When we perform an A/C repair on your 2012 Mercedes-Benz GL350, 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 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 GL350 A/C recharges.

Common Mercedes-Benz GL350 A/C Problems

Hot air is a common Mercedes-Benz GL350 A/C problem, but it’s not the only issue you might encounter. Other common A/C problems include 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 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 GL350? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your GL350.
