How can I make my SL450 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 do I get hot air from my SL450 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.

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 SL450’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does my SL450 A/C run 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 SL450.

My SL450’s A/C smells like vinegar! What can cause that?

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 SL450 to have a vinegar-like smell.

What is causing my SL450’s A/C to only work when the car is in motion?

Damaged or worn components in your SL450’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.

Mercedes-Benz SL450 A/C Repair

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my Mercedes-Benz SL450 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 2018 Mercedes-Benz SL450 A/C systems. Bring your Mercedes-Benz SL450 to your local Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2018 Mercedes-Benz SL450 A/C system to evaluate what repairs are necessary (if any). 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.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz SL450 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

SL450 A/C Recharge

Let's say we repair your 2018 Mercedes-Benz SL450 A/C system. We will also perform 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. Next, they will evacuate the system according to Mercedes-Benz's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you’re good to go. Our technicians are trained to efficiently perform 2018 Mercedes-Benz SL450 A/C recharges.

Other Mercedes-Benz SL450 A/C Problems

You may think warm air is the only potential Mercedes-Benz SL450 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. 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. Are you breathing in some “interesting” new odors in your 2018 Mercedes-Benz SL450? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your SL450 — without all the sweat puddles!
