Hello, I have two citroen c3's in the workshop, one always gives me an alarm on the fog lights even though everything is working correctly, the other starts the rear wiper with relative water even if I don't touch anything while driving, then even after charging the a/c system when I press the automatic climate button the current on the compressor only arrives for two or three seconds and then it arrives after 6-10 minutes if I'm always on. What could it be? I checked with the computer while driving to see if the signal from the bsi for the rear wiper control was starting, but when I try it seems to work fine.
