How can I make my 500SEC air conditioner colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

Why is my 500SEC 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?

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 500SEC’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Is my 500SEC A/C powered by gas?

The air conditioning system in your 500SEC 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.

What can cause the A/C in my 500SEC to smell like vinegar?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your 500SEC creates a breeding environment for microorganisms.

Why won’t my 500SEC’s A/C cool the vehicle when the car is stopped?

There could be issues with one or more components in the air conditioning or electrical system. Your 500SEC may have a faulty cooling fan or low refrigerant.

A/C Service for Mercedes-Benz 500SEC

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. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz 500SEC?" Firestone Complete Auto Care — that’s who! We know Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 1984 Mercedes-Benz. Come to your local Firestone Complete Auto Care in your Mercedes-Benz 500SEC

During this initial A/C performance check, we’ll look at the state of your 1984 Mercedes-Benz 500SEC’s A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. 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" is a machine that's run along parts of your Mercedes-Benz 500SEC A/C system that can detect any refrigerant fumes that might be leaking out from the system. If your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your 500SEC

While your 1984 Mercedes-Benz 500SEC’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. Finally, we’ll recharge the A/C system with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. Our technicians are trained to efficiently perform 1984 Mercedes-Benz 500SEC A/C recharges.

Common Mercedes-Benz 500SEC A/C Problems

Hot air is a common Mercedes-Benz 500SEC A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is 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. Are you breathing in some “interesting” new odors in your 1984 Mercedes-Benz 500SEC? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. 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 500SEC — without all the sweat puddles!
