Well I recently picked up a 2000 Cherokee Classic. The windows do not roll down, and the fan controls do not work either. I did a search, and made sure my window switch was good, It was, I have power going to it as well. I also checked my ignition switch, and got nothing as well.

Any Ideas will be greatly appreciated.

 

Check your relays.

 

x2 on the relays. make sure you have power to them first.

 

I checked all the relays an fuses before I checked the window switch, and the ignition switch. What's the possibility of it being a ground?

 

Bump

 

If you have power going to the window switch, I'd pop the door panel off and see what happens when I run power directly to the window motor. That will at least tell you if it's the motor or potentially the wiring.

 

As far as the fan goes, check the ballast resistor in the duct in the passenger footwell.
