Fan Switch Won't Work

Ok i've had the manual fan switch on the car for quite some time now and last night it wouldnt turn on, no problem I think, get it the garage today and redo the wire all pretty like, and it still wont work. When I flip my switch I can hear a clicking noise from under the hood but the fan wont turn on. The blade moves freely so I know the motor isnt shot and the computer still turns it on, just I cant, WTF. Can I hook up a wire to one of the three that go to the fan itself or no? Any help would be appreciated.

OK, you should be tapped into wire #17 on the big harness that is near the overflow bottle. Turn the key to the on position. Take the wire that is tapped into the harness and touch it to the (-) terninal of the battery. Fan should come on. If it does then trace the wire all the way to the switch and make sure all looks good there. If the fan does not come on when you ground the wire manually, you have fan or PCM problems.
