Power window issues

[Mreetz]

I have an '84 K5 with no power to the window for some reason. It won't work to operate either the drivers side or passengers side window. Power lock works tho.......
I replaced the switch with no change. Is there a seperate fuse for this?

Yes, there is a fuse for the power windows. You can always check for voltage at the switch by either using a digital multimeter or a test light. There should be a hot wire (12 vdc) that is constant on the switch.

also verify that the wiring going to the drivers side switch is not loose/broken/corroded as that is the master switch. I had the same issue with my truck where one rear passenger window was not working and found that a wire connecting that motor to the drivers master control was corroded

I think it is a power wire issue cause I can get the passenger side window to work from that side.

Check all your connections, Positive and Negative (ground). At the door hinge does your wiring go through a bellowed hose or is it a icky-poo ( ) exposed set of connections that only make contact when the door is closed?

It goes through a bellowed hose.
