Mercedes Benz AC reset is not a routine form of maintenance. Meaning, unless the need demands it, you don’t necessarily have to do an AC reset. In fact, some might have been using their Mercedes-Benz cars for years before ever having a need to reset the AC.

HOW TO DO A MERCEDES BENZ AC RESET

Certain drivers freak out when they hear about a Mercedes Benz reset because they imagine having to get their hands dirty and think it’s a difficult task. But on the contrary, it’s a simple process. Follow these three simple steps to rest the AC of your car;

STEP ONE: INSERT YOUR KEY INTO THE IGNITION BUTTON

The first step is to insert your key into its rightful slot in the car. Turn the ignition cylinder to position ‘2’. This is the highest point that the cylinder can go without activating the engine. Starting the car will prevent you from doing an effective Mercedes Benz AC reset

STEP TWO: PRESS THE RECIRCULATRmE AIR AND DEFROST AIR BUTTONS SIMULTANEOUSLY

Moving further, press and hold the recirculate air button and the defrost air button at the same time. The defrost button has three lines going through it, while the recirculated air button has a picture of a car with a curved line through it. You will have to hold down these two buttons for about 5-10 seconds, or rather until the LED lights of both buttons start flashing. The lights will start flashing to let you know you have held the bottoms long enough.

STEP THREE: WAIT

Normally, the LED lights won’t keep flashing for too long. Wait for 45 to 60 seconds for the LED lights to stop flashing. Then turn off the car.

After this, wait for another 60 seconds, before you switch on the Engine of the car to allow the AC reset to reach completion. Your AC should be back and running normally.
