A/C Service for Mercedes-Benz 350SD

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz 350SD A/C?” 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 1991 Mercedes-Benz A/C systems. Steer your Mercedes-Benz 350SD to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 1991 Mercedes-Benz 350SD A/C system to see if repair work is required. 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" is a machine that's run along parts of your Mercedes-Benz 350SD A/C system that can identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your 350SD

While your 1991 Mercedes-Benz 350SD’s air conditioner is being serviced, 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. Finally, we’ll recharge the A/C system with new refrigerant and once we’ve done a final test on the system ourselves, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 1991 Mercedes-Benz 350SD A/C recharges.

Troubleshooting Mercedes-Benz 350SD A/C Problems

You may think warm air is the only potential Mercedes-Benz 350SD A/C problem you’ll have, but you may notice other issues, too. Another common A/C problem is weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. 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. And smelly A/C in a 1991 Mercedes-Benz 350SD? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our technicians will work to solve your A/C problems to the best of their ability. We’re here to help you get back on the road in your 350SD — without all the sweat puddles!

Frequently Asked Questions for 1991 Mercedes-Benz 350SD A/C Systems

  • Can I make my 350SD 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 350SD A/C blowing hot air? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • What causes A/C system leaks? 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 350SD’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Is my 350SD A/C powered by gas? 350SD air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.
  • What can cause the A/C in my 350SD to 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 350SD to produce a vinegary odor.
  • Why won’t my 350SD’s A/C cool the vehicle when the car is stopped? Damaged or worn components in your 350SD’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.
