Driver side power window not working
I have a 2000 Tahoe ("New Body Style") that the driver side window just quit working the other day. No sounds coming from the window, it doesn't even try to go up and down. All of the other windows can be controlled from the master switch, just not the driver's window. If I apply 12 volts to the motor, it goes up and down. I checked for voltage at the connector to the motor, and nothing happens when I opersate the switch. Thought the switch might be bad, so I replaced it with a new master switch. Now I have a nice lighted switch, but no response from the window. Any idea how to troubleshoot the door wire harness?

Re: Driver side power window not working
I checked from the switch to the motor, no open wires, no shorts that I can find.

Re: Driver side power window not working
the wires at the driver door window motor have color correct ???? follow those wires back to the driver door window control switch .. make sure both are good and use your meter to check.measure at swith that you get 12 volts and a ground return so that you are sure those wires are good.

I couldn't find any open wires, traced everything back to the block on the fuse panel. I did verify that the motor was OK, took it out and ran it from the passenger door switch without any problem. Did the same with the passenger motor on the driver side, did not work, just like the original driver side motor. Getting a little frustrated.at this point, but not ready to give up and take it to a dealer. |

If the 12 volts is not at the switch wire going to the door window motor that does not work then the switch is bad or the connector at the door switch going to the door window motor is open. when you push on the door window switch measure for 12 volts with your meter using a good ground .measure both sides of the motor of this door window to see if you have 12 volts on both wires. also measure at the switch where the wires go to this window motor . |

Re: Driver side power window not working
the mirror does not work because the control pad needs cleaning. this is just like a tv remote control. take it apart and very carefully clean those pad contacts with some alcohol and a Q tip.
on the door window with 12 volts at the door master switch the driver door window motor not working and your not able to figure it out is weird . not much there to get that complicated. using a volt / ohm meter this should be a quick fix. |

Re: Driver side power window not working
OK, so here it is now - I found the issue. The dark green wire (RAP) to the switch was cut at the door / a-pillar junction. Connecting a jumper here allowed the window to function normally. Now, do I repair this wire, or just buy a new door harness? At 340K miles, that may just be the first of many wires in that door harness that are ready to give up.

from time to time this will occur. replacing a wire harness is not what would be done with repair issues like this. good luck with your repair . good job. |
