my harness was hacked all up all factory plugs cut off, i replaced all the factory plugs and fixed the wiring, but still nothing, i tried working with the box on the inside of the driver fender well nothing, the relay there nothing, so i figured out that by sticking my test light in the back of the factory switch it would act as a ground, one would roll the window up, one would roll it down, and the others wouldnt do anything, so after thinking about it for a bit it hit me to use it as a ground on the other wires that didnt roll it up or down just by touching it, and try to use the switch, the first wire i tried was the one i needed, i just stripped a wire about 1.5 inches stuck it into the port where the blue wires meet in the plug and ran the ground to my stereo ground, i rolled the window up and down literally 10 to 12 times over and over to make sure nothing was getting hot or anything and it worked perfectly, i went to my friends house that has had the same problem for years and it fixed his too, i had asked alot of people how to fix this and noone knew so i thought i would share hope this helps!!
