How can I make my CLS400 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 CLS400 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?

A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your CLS400's A/C system.

Does my CLS400 A/C run on gas?

The air conditioning system in your CLS400 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.

What can cause the A/C in my CLS400 to smell like vinegar?

If the air conditioning in your CLS400 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.

What is causing my CLS400’s A/C to only work when the car is in motion?

There could be issues with one or more components in the air conditioning or electrical system. Your CLS400 may have a faulty cooling fan or low refrigerant.

Mercedes-Benz CLS400 A/C Repair

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. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz CLS400?" Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2017 Mercedes-Benz CLS400 A/C systems. Steer your Mercedes-Benz CLS400 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2017 Mercedes-Benz CLS400 A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. 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" is a machine that's run along parts of your Mercedes-Benz CLS400 A/C system that can identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

CLS400 A/C Recharge

When we perform an A/C repair on your 2017 Mercedes-Benz CLS400, 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 2017 Mercedes-Benz CLS400 A/C recharges.

Other Mercedes-Benz CLS400 A/C Problems

Hot air is a common Mercedes-Benz CLS400 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is 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. And smelly A/C in a 2017 Mercedes-Benz CLS400? 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. So, chill out. We're here to help you get the blast back in your CLS400’s A/C!
