Well I just put the nose of my E-39 back on with a freshly WD-40d pusher fan (btw never buy a new fan at $360.00 when chances are it just needs to be cleaned ) The problem is it works on all three speeds (off a battery) when I plug it into the car the A/C will trigger low speed, but the car overheats with NO fan. So I am guessing there must be a problem with either the fuse, relay, or temp switch. I just need some suggestions, and the location of the relay and fuse PLEASE!!! I know where the temp switch is. I figured I would start with the cheap stuff first fuse-relay-temp switch.
Any help is truly appreciated.
