    Do you have a wiring scematic? I would see if the two are tied in together, also look for loose grounds. If you have a volt meter make sure the wire has continuity even though it looks good dosen't mean it is. If your fuses are OK and there is no power at either the fan/resistor or wiper motor check for power at the switches.....

    As I do not have first hand knowlage of your rig or a scmatic in front of me these are best guess answers only. Just check the basics first and go from there.
