you didn't really identify which vehicle this is so I'm taking a guess on this. is this auto temp control and what vehicle is it? if it's auto tem p then the diagram I'm sending isn't any good. but heck to make sure diode at clutch is good then check relay and fusible link. It may be the relay pointed out in pic as well. if this iauto temp where you set the temp then disregard everything here and give me the correct info.
