How can I make my E300 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 is my E300 A/C blowing hot 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?

Over the years, the rubber seals and gaskets in your E300’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.

Does my E300 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 E300.

Why does the A/C in my E300 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 E300 to produce a vinegary odor.

Why does my E300’s A/C only work when the car is moving?

There could be issues with one or more components in the air conditioning or electrical system. Your E300 may have a faulty cooling fan or low refrigerant.

A/C Service for Mercedes-Benz E300

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like it's burning your hands. That puddle in the driver’s seat? Sweat. Ugh. “Who can fix my Mercedes-Benz E300 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know our way around Mercedes-Benz vehicles, and our trained technicians can identify and repair issues with 2017 Mercedes-Benz A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz E300

In this A/C performance inspection, we’ll check out the current condition of your 2017 Mercedes-Benz E300 A/C system to determine whether repair work is needed. This check includes a visual inspection, performance test, and pressure and leak test. If we think there might be a leak, we'll run a special U/V dye through the system or use 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 E300 A/C system to detect any refrigerant fumes that might be leaking out from the system. If there's a leak, we'll find it and fix it.

E300 A/C Recharge

When we perform an A/C repair on your 2017 Mercedes-Benz E300, we’ll also do 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). Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. To finish, we’ll add new refrigerant to recharge the A/C system, and once the technician tests the cool blast for themselves, you’re good to go. Our technicians are trained to efficiently perform 2017 Mercedes-Benz E300 A/C recharges.

Troubleshooting Mercedes-Benz E300 A/C Problems

You may think warm air is the only potential Mercedes-Benz E300 A/C problem you’ll have, but you may notice other issues, too. 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. An A/C system that starts off blowing cold air but then turns warm can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. Are you breathing in some “interesting” new odors in your 2017 Mercedes-Benz E300? 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 E300 — without all the sweat puddles!
