2000 Jeep Cherokee power windows only work from the drivers

Question 1. For some reason all the power windows in my 2000 jeep cherokee will only work from the drivers side control. However, once in a while when it is raining, the window switches will light up on the remaining doors and the windows will work from the other door controls. Then once the jeep becomes dry, the windows only work from the drivers side again. My guess would be a short but i have no clue where. What do you guys think?

Question 2. I need to replace my blower motor resistor, where is it located on a 2000 jeep cherokee?
