How can I make my E320 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 E320 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?

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 E320's A/C system.

Does the A/C in my E320 rely on gas?

The air conditioning system in your E320 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 E320’s A/C smells like vinegar! What can cause that?

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 E320 to produce a vinegary odor.

Why does my E320’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 E320 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

A/C Repair Service for Your Mercedes-Benz E320

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. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz E320 A/C?” Easy — Firestone Complete Auto Care! We’ve got experience with Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 2009 Mercedes-Benz E320 A/C systems. Bring your Mercedes-Benz E320 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2009 Mercedes-Benz E320’s A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a 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. A "sniffer" is a machine that's run along parts of your Mercedes-Benz E320 A/C system that can detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

A/C Recharge for Mercedes-Benz E320

While your 2009 Mercedes-Benz E320’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 use Mercedes-Benz’s specifications to evacuate the system. 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 ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2009 Mercedes-Benz E320 A/C recharges.

Troubleshooting Mercedes-Benz E320 A/C Problems

Warm air isn't the only Mercedes-Benz E320 A/C problem you may encounter. 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. 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2009 Mercedes-Benz E320? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your E320 — without all the sweat puddles!
