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?

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?

To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your S420’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my S420 A/C use 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 S420.

What can cause the A/C in my S420 to smell like vinegar?

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 won’t my S420’s A/C cool the vehicle when the car is stopped?

If your A/C only works when the vehicle is moving, there could be a problem with part of your S420’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

Mercedes-Benz S420 A/C Repair

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. “Who can fix my Mercedes-Benz S420 A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We know our way around Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 1997 Mercedes-Benz S420 A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz S420

During this initial A/C performance check, we’ll look at the state of your 1997 Mercedes-Benz S420’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 any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called 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 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 1997 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. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 1997 Mercedes-Benz S420 A/C recharges.

Other Mercedes-Benz S420 A/C Problems

You may think warm air is the only potential Mercedes-Benz S420 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also 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. An A/C system that starts off blowing cold air but then turns warm may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 1997 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.
