How can I make my GLS350d 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 is my GLS350d 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.

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 GLS350d’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does running the A/C in my GLS350d use gasoline?

The air conditioning system in your GLS350d 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 GLS350d smell 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 GLS350d to produce a vinegary odor.

Why won’t my GLS350d’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 GLS350d is moving. You may be low on refrigerant, or the cooling fan could be faulty.

Mercedes-Benz GLS350d A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. 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 GLS350d?" Firestone Complete Auto Care — that’s who! We know Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2017 Mercedes-Benz GLS350d A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz GLS350d

During an A/C performance check, we'll determine the condition of your 2017 Mercedes-Benz GLS350d 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" is a machine that's run along parts of your Mercedes-Benz GLS350d A/C system that can 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 GLS350d

Let's say we repair your 2017 Mercedes-Benz GLS350d A/C system. We will also perform 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 ready to get back on the road. Our technicians are trained to efficiently perform 2017 Mercedes-Benz GLS350d A/C recharges.

Common Mercedes-Benz GLS350d A/C Problems

Warm air isn't the only Mercedes-Benz GLS350d A/C problem you may encounter. Typical A/C problems also 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 can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 2017 Mercedes-Benz GLS350d? 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 GLS350d.
