Can I make my E400 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.

What’s making my E400 A/C put out warm air?

If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

What causes A/C system leaks?

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 E400’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does the A/C in my E400 use gas?

The air conditioning system in your E400 does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.

My E400’s A/C smells like vinegar! What can cause that?

If the air conditioning in your E400 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.

Why does my E400’s A/C only work when the car is moving?

A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your E400 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

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 E400 A/C?” Firestone Complete Auto Care can! We know Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2017 Mercedes-Benz A/C systems. Steer your Mercedes-Benz E400 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2017 Mercedes-Benz E400’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.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz E400 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.

Recharge the A/C in Your E400

Let's say we repair your 2017 Mercedes-Benz E400 A/C system. We will also perform an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Next, they will evacuate the system according to Mercedes-Benz's recommendations. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you’re good to go. Our technicians are trained to efficiently perform 2017 Mercedes-Benz E400 A/C recharges.

Troubleshooting Mercedes-Benz E400 A/C Problems

Hot air is a common Mercedes-Benz E400 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. And smelly A/C in a 2017 Mercedes-Benz E400? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. We’re here to help you get back on the road in your E400 — without all the sweat puddles!
