Replace the Pressure Switch for the Air Conditioning Compressor on the Audi A6

Model: Audi A6 MK 3, C6 - Years 2004-2012
Part: Air conditioning

To replace the air conditioning pressure switch, which controls the fan motor failure, on the Audi A6, open the hood and remove the plastic cover at the front of the engine bay. Below, you will find the radiator and, hidden at the back - as shown in the video - the pressure switch that needs to be replaced. You will need to disconnect the connectors attached to it. Also, test the wires with a multimeter to ensure they are all functioning properly. Unfortunately, accessing this component is not easy, but once you replace it, the fan motor will start working again, and consequently, the air conditioning in the Audi A6 will function as well.
