The cooling fan electrical circuit is reletively simple. Refer to M:18:10 in the workshop manual. Some of the more common problems are: Burnt jumper or connections in the relay block Blown #5 fuse (test it even if it looks good) Bad grounds for fan motors Bad otterstat (temp switch) Bad fan motors Use a test light or meter to a GOOD ground and see where you have power. Jump the otterstat switch with a paper clip. (Keep one in the car at all times for emergency use.)
