C5 2005. Compressor clutch coil. Power supply only 10.8V

Post by Bonjour »

Hi
I have an unusual problem with the air conditioning. Compressor clutch coil does not engage. The coil is operational, it works after applying voltage directly from the battery. I measured the voltage on the coil power harness and it is strange. is only 10.8V. The voltage appears when the engine is started and remains even after turning off the AC function on the driver's computer panel? Why is it not <14 V? What could be the reason?
