I have a 94 grand Cherokee Laredo 6 cylinder 4.0 l. Only the front driver side window controls work. The switches in all the other doors are still good (I tested them with a multi meter) but they will not roll up or down the windows only the main front driver side will. I thought the window lock switch was broken but after taking it apart and shorting it out I still had the same problem. Any suggestions
-Thanks

Clean all the switches the same way. It will help.

 

Clean them up. If that don't get it, then check then check the wiring in the driver door jamb. Very common to have a broken wire in there. All the switches are wired from the master. Also there are junctions under both front seats. They have a tendency to turn to a green mess. Good luck and please post back what you find.
