A/C Service for Mercedes-Benz S420

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. Sweat soaks the driver's seat. “Who can fix my Mercedes-Benz S420 A/C?” you wonder, as the sun beats through the windshield. 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 1994 Mercedes-Benz. Bring your Mercedes-Benz S420 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1994 Mercedes-Benz S420 A/C system to evaluate what repairs are necessary (if any). This check will include an examination of system pressure, a visual inspection, and a leak test. If we think there might be a leak, we'll run a special U/V dye through the system or use 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 detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

S420 A/C Recharge

While your 1994 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 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 once we’ve done a final test on the system ourselves, you're ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 1994 Mercedes-Benz S420 A/C recharges.

Common Mercedes-Benz S420 A/C Problems

Warm air isn't the only Mercedes-Benz S420 A/C problem you may encounter. 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. If your A/C system blows cold air first but then it turns warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 1994 Mercedes-Benz S420? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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.

Frequently Asked Questions for 1994 Mercedes-Benz S420 A/C Systems

  • Can I make my S420 air conditioner colder? Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.
  • Why do I get hot air from my S420 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? 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 S420's A/C system.
  • Does my S420 A/C run on gas? S420 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.
  • Why does my S420 have a vinegary smell coming from the A/C? 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 S420 creates a breeding environment for microorganisms.
  • Why does my S420’s A/C only work when the car is moving? There could be issues with one or more components in the air conditioning or electrical system. Your S420 may have a faulty cooling fan or low refrigerant.
