A/C Repair Service for Your Mercedes-Benz 420SEL

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 lava. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz 420SEL A/C?” Firestone Complete Auto Care can! We know Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 1989 Mercedes-Benz A/C systems. Steer your Mercedes-Benz 420SEL to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1989 Mercedes-Benz 420SEL’s A/C system to determine whether repair work is needed. 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 420SEL A/C system to identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

420SEL A/C Recharge

While your 1989 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. 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 good to go. We want you to be comfortable in your car, so we train our technicians to perform 1989 Mercedes-Benz 420SEL A/C recharges.

Troubleshooting Mercedes-Benz 420SEL A/C Problems

You may think warm air is the only potential Mercedes-Benz 420SEL A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. 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. Are you breathing in some “interesting” new odors in your 1989 Mercedes-Benz 420SEL? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our technicians will work to solve your A/C problems to the best of their ability. So, chill out. We're here to help you get the blast back in your 420SEL’s A/C!

Frequently Asked Questions for 1989 Mercedes-Benz 420SEL A/C Systems

  • How do I make my 420SEL air conditioning 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 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.
  • What can cause an A/C system leak? Over the years, the rubber seals and gaskets in your 420SEL’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.
