A/C Repair Service for Your 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. 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 Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 1998 Mercedes-Benz. Steer your Mercedes-Benz S420 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1998 Mercedes-Benz S420 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.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz S420 A/C system to detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

A/C Recharge for Mercedes-Benz S420

When we perform an A/C repair on your 1998 Mercedes-Benz S420, 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 use Mercedes-Benz’s specifications to evacuate the system. 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 all set. We want you to be comfortable in your car, so we train our technicians to perform 1998 Mercedes-Benz S420 A/C recharges.

Troubleshooting Mercedes-Benz S420 A/C Problems

Hot air is a common Mercedes-Benz S420 A/C problem, but it’s not the only issue you might encounter. Other common A/C problems include weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. If your A/C system blows cold air first but then it turns warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 1998 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 trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your S420’s A/C!

Questions About 1998 Mercedes-Benz S420 A/C Systems

  • How 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? An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.
  • What causes A/C system leaks? Over the years, the rubber seals and gaskets in your S420’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.
  •  Does running the A/C in my S420 use gasoline? 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.
  • My S420’s A/C smells like vinegar! What can cause that? Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your S420 to have a vinegar-like smell.
  • Why does my vehicle have to be moving for my S420’s A/C to work? 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.
