When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz 420SEL A/C?” Easy — Firestone Complete Auto Care! We’ve got experience with Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 1991 Mercedes-Benz. Bring your Mercedes-Benz 420SEL to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1991 Mercedes-Benz 420SEL’s A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and leak test. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz 420SEL 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.

Recharge the A/C in Your 420SEL

While your 1991 Mercedes-Benz 420SEL’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. Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians know how to keep your A/C in tip-top shape with 1991 Mercedes-Benz 420SEL A/C recharges.

Common Mercedes-Benz 420SEL A/C Problems

Warm air isn't the only Mercedes-Benz 420SEL A/C problem you may 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 suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 1991 Mercedes-Benz 420SEL? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. So, chill out. We're here to help you get the blast back in your 420SEL’s A/C!

Questions About 1991 Mercedes-Benz 420SEL A/C Systems

  • How do I make my 420SEL 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.
  • Why do I get hot air from my 420SEL 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 420SEL's A/C system.
