sounds like an "open circuit". i.e there is a break in the main power wire to the door somewhere. open the  opposite door and test to find what color wire is being used. find that wire in your faulty door and test for power. if there is no power you have an "open" in that wire, meaning the little copper strands inside the insulation are broken or the wire is cut. using an inline fuse holder with a 5 amp fuse connect to a power source and then to the wire in question right at your switch, then test the locks and window. if all works then you'll know thats your problem. how to repair the wire(or run a new one) is now all up to you.

thank u for the insight the problem is all fixed now i really appreciate it
