How can I make my 500SL 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 500SL A/C blowing hot air?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

What can cause an A/C system leak?

Over the years, the rubber seals and gaskets in your 500SL’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 the A/C in my 500SL rely on 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 500SL.

What does it mean if the A/C in my 500SL 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 500SL to have a vinegar-like smell.

Why does my vehicle have to be moving for my 500SL’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 500SL’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Repair Service for Your Mercedes-Benz 500SL

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like lava. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz 500SL?" Firestone Complete Auto Care can! We know Mercedes-Benz vehicles, and our technicians are qualified to diagnose and repair 1990 Mercedes-Benz 500SL A/C systems. Come to your local Firestone Complete Auto Care in your Mercedes-Benz 500SL

During this initial A/C performance check, we’ll look at the state of your 1990 Mercedes-Benz 500SL’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" is a machine that's run along parts of your Mercedes-Benz 500SL A/C system that can identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

Recharge the A/C in Your 500SL

While your 1990 Mercedes-Benz 500SL’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. Next, they will evacuate the system according to Mercedes-Benz's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, and after one final test to be sure the system is cooling properly, you're ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 1990 Mercedes-Benz 500SL A/C recharges.

Common Mercedes-Benz 500SL A/C Problems

Warm air isn't the only Mercedes-Benz 500SL 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. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 1990 Mercedes-Benz 500SL? 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 500SL’s A/C!
