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.

Does my 420SEL A/C run on gas?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your 420SEL.

What can cause the A/C in my 420SEL to smell like vinegar?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your 420SEL to produce a vinegary odor.

Why won’t my 420SEL’s A/C cool the vehicle when the car is stopped?

There could be issues with one or more components in the air conditioning or electrical system. Your 420SEL may have a faulty cooling fan or low refrigerant.

A/C Service for 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 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!
