Mercedes-Benz S420 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like lava. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz S420 A/C?” Firestone Complete Auto Care — that’s who! We know our way around Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 1996 Mercedes-Benz A/C systems. Bring your Mercedes-Benz S420 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1996 Mercedes-Benz S420’s 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 S420 A/C system to identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your S420

While your 1996 Mercedes-Benz S420’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. Then, they’ll use Mercedes-Benz’s specifications to evacuate the system. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 1996 Mercedes-Benz S420 A/C recharges.

Common Mercedes-Benz S420 A/C Problems

You may think warm air is the only potential Mercedes-Benz S420 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. 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. Are you breathing in some “interesting” new odors in your 1996 Mercedes-Benz S420? 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. Don’t sweat it — we’re here to help you chill out again in your S420.

Questions About 1996 Mercedes-Benz S420 A/C Systems

  • How do I make my S420 air conditioning 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.
  • What’s making my S420 A/C put out warm 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.
  • What causes A/C system leaks? 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 S420’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 S420 rely on gas?  The air conditioning system in your S420 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 does it mean if the A/C in my S420 smells like vinegar? If the air conditioning in your S420 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 S420’s A/C to only work when the car is in motion? Damaged or worn components in your S420’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.
