Hi, the fan of my climate for the third row of seats does not want to start. At the fan control are measured 12 volts at the entrance. However, no 12v at the output for the fan come out. If I take the input 12 volts directly on the fan bridge then the fan jumps perfectly. I thought the fan control is broken and I needed a climate box shot and the fan control rebuilt. However, the same picture. I can now only explain that the fan control is broken. control signals (left both lines in the circuit diagram) don’t fit. I don’t know how to look like, how to check them exactly. Does anyone know advice? Edit: my pictures are simply not taken over. Will try again this evening on the computer.
