How do I make my 300CD air conditioning 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 300CD 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.

How does my A/C system get a 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 300CD’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Is my 300CD A/C powered by gas?

Your 300CD’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

Why does my 300CD have a vinegary smell coming from the A/C?

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 300CD creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my 300CD’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 300CD’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Service for Mercedes-Benz 300CD

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. “Who can fix my Mercedes-Benz 300CD A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care can! We know Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 1985 Mercedes-Benz. Bring your Mercedes-Benz 300CD to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1985 Mercedes-Benz 300CD A/C system to determine whether repair work is needed. 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 300CD A/C system that can detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

300CD A/C Recharge

When we perform an A/C repair on your 1985 Mercedes-Benz 300CD, 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 perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. Our technicians know how to keep your A/C in tip-top shape with 1985 Mercedes-Benz 300CD A/C recharges.

Common Mercedes-Benz 300CD A/C Problems

Hot air is a common Mercedes-Benz 300CD A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is 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 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 1985 Mercedes-Benz 300CD? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. Don’t sweat it — we’re here to help you chill out again in your 300CD.
