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 do I get hot air from my GL550 A/C?

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 running the A/C in my GL550 use gasoline?

Your GL550’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.

Why does my GL550 have a vinegary smell coming from the A/C?

If the air conditioning in your GL550 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.

Why does my vehicle have to be moving for my GL550’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your GL550 may have a faulty cooling fan or low refrigerant.

A/C Service for 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. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz GL550 A/C?” Firestone Complete Auto Care — that’s who! We know our way around Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2016 Mercedes-Benz. Bring your Mercedes-Benz GL550 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2016 Mercedes-Benz GL550’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” 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 identify points where refrigerant fumes could be escaping 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 2016 Mercedes-Benz GL550’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. 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 2016 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. 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2016 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. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your GL550.
