How do I make my 350SDL air conditioning 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 350SDL A/C?

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.

How does my A/C system get a leak?

Over the years, the rubber seals and gaskets in your 350SDL’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 350SDL 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 350SDL.

What does it mean if the A/C in my 350SDL smells like vinegar?

Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your 350SDL to have a vinegar-like smell.

Why does my vehicle have to be moving for my 350SDL’s A/C to work?

If your A/C only works when the vehicle is moving, there could be a problem with part of your 350SDL’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

Mercedes-Benz 350SDL A/C Repair

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz 350SDL A/C?” Firestone Complete Auto Care — that’s who! We’ve got experience with Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 1991 Mercedes-Benz 350SDL A/C systems. Steer your Mercedes-Benz 350SDL to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1991 Mercedes-Benz 350SDL’s A/C system to determine whether repair work is needed. This check will include an examination of system pressure, a visual inspection, and a 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 350SDL A/C system to detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for Mercedes-Benz 350SDL

Let's say we repair your 1991 Mercedes-Benz 350SDL 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 the technician tests the cool blast for themselves, you're ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 1991 Mercedes-Benz 350SDL A/C recharges.

Troubleshooting Mercedes-Benz 350SDL A/C Problems

Warm air isn't the only Mercedes-Benz 350SDL 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 be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. And smelly A/C in a 1991 Mercedes-Benz 350SDL? 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. So, chill out. We're here to help you get the blast back in your 350SDL’s A/C!
