Audi S3 2001 I have a problem with the climate control unit. It is dead.
long story short,the turbo leaked and melted the pressure switch G65 and the climate control unit went dead. I have replaced G65 and re-gassed. The control unit is still dead.
I have traced all the wires and there are no apparent shorts.I was told it could be relay 1j0919506k.
having checked this i could not find a problem but replaced it never the less.
What I find is --on the relay J293 if the (4 pin side)power plug is in and i check the 14 pin side(without the plug in) I get power to all the 14 terminals,when i plug in the plug and check the wires directly behind the plug there is no power.
Also if i put power directly to G65 all the fans and pump ect start working?
