How do I make my S400 air conditioning 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 S400 A/C?

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 S400’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my S400 A/C run on gas?

Your S400’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.

My S400’s A/C smells like vinegar! What can cause that?

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 S400 to produce a vinegary odor.

Why won’t my S400’s A/C cool the vehicle when the car is stopped?

Damaged or worn components in your S400’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 S400

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz S400 A/C?” Firestone Complete Auto Care can! We know our way around Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2013 Mercedes-Benz. Bring your Mercedes-Benz S400 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2013 Mercedes-Benz S400’s A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. 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” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Mercedes-Benz S400 A/C system to identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

A/C Recharge for Mercedes-Benz S400

While your 2013 Mercedes-Benz S400’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 once the technician tests the cool blast for themselves, you’re all set. Our technicians are trained to efficiently perform 2013 Mercedes-Benz S400 A/C recharges.

Troubleshooting Mercedes-Benz S400 A/C Problems

Warm air isn't the only Mercedes-Benz S400 A/C problem you may encounter. Other common A/C problems include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. 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. And smelly A/C in a 2013 Mercedes-Benz S400? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. We’re here to help you get back on the road in your S400 — without all the sweat puddles!
