What fuse and which wire do I use to hook my cooling fans up to.

Veronica: It sounds as tho you have a *control side* circuit issue with the fans. If the fan motors can be engaged by taking them directly off the battery then there is nothing wrong with them themselves. Try this...(if you can't do it yourself get someone who can)....locate the relays for the fan motors (they should be in the electrical center under the hood)....pull the relays from their sockets....with a jumper wire bridge the 12v battery source terminal directly to the terminal that feeds the motors. The battery should be pin #30 on the relay blade terminal and the fan motors should be pin#87. If the fans come on by jumpering then there is a problem on the *control* side that the ECM takes control of. That would need to be diagnosed to locate the source of the problem. It could be faulty wiring/failed ECM sensor or something more serious, but it's NOT impossible to correct.
