Window problems

[DPatin]

Hey guys,

New to here. I have a 99 Gmc 2500 crew cab. The windows only roll up and down with the driver side switch. I just replaced the passenger side switch just to see if that would work, but still doesn't. Any help would be appreciated.

probably no power to the passenger switch. may be broken wire where the wires go from the body to the door. slice the rubber boot with a razor knife and take a look. sometimes the wire breaks but not the insulation so give them a tug and see if they stretch. that power wire may originate in the drivers door which is more common place for the broken wires as it sees more use
