How can I make my GL550 air conditioner colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

Why is my GL550 A/C blowing hot air?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

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 GL550’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does the A/C in my GL550 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 GL550.

Why does the A/C in my GL550 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 GL550 to have a vinegar-like smell.

Why won’t my GL550’s A/C cool the vehicle when the car is stopped?

Damaged or worn components in your GL550’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 GL550

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz GL550?" Firestone Complete Auto Care can! We know Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2013 Mercedes-Benz. Bring your Mercedes-Benz GL550 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2013 Mercedes-Benz GL550 A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and 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” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Mercedes-Benz GL550 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 GL550

While your 2013 Mercedes-Benz GL550’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and once the technician tests the cool blast for themselves, you're ready to get back on the road. Our technicians are trained to efficiently perform 2013 Mercedes-Benz GL550 A/C recharges.

Troubleshooting Mercedes-Benz GL550 A/C Problems

You may think warm air is the only potential Mercedes-Benz GL550 A/C problem you’ll have, but you may notice other issues, too. Other common A/C problems include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2013 Mercedes-Benz GL550? 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 technicians will work to solve your A/C problems to the best of their ability. We’re here to help you get back on the road in your GL550 — without all the sweat puddles!
