How can I make my S400 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 S400 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?

Over the years, the rubber seals and gaskets in your S400’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.

Is my S400 A/C powered by gas?

S400 air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.

What can cause the A/C in my S400 to smell like vinegar?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your S400 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my S400’s A/C to work?

A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your S400 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Service for Mercedes-Benz S400

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. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz S400 A/C?” Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2010 Mercedes-Benz A/C systems. Bring your Mercedes-Benz S400 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2010 Mercedes-Benz S400 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 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 detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

S400 A/C Recharge

When we perform an A/C repair on your 2010 Mercedes-Benz S400, 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. Finally, we’ll recharge the A/C system 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 2010 Mercedes-Benz S400 A/C recharges.

Other Mercedes-Benz S400 A/C Problems

Hot air is a common Mercedes-Benz S400 A/C problem, but it’s not the only issue you might encounter. Typical A/C problems also include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2010 Mercedes-Benz S400? 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. We’re here to help you get back on the road in your S400 — without all the sweat puddles!
