Wire identification 2008 Tahoe

[hoytheld]

All,

Have a 2008 hoe, LTZ.

I have lost power to the drivers door functions. If I pinch and twist the boot in-between the door and door jam, I can get temporary power to the door. So, this leads me to believe that after repeated opening and closing of the door, the feed wire is broke.

Does anyone know which color the feed wire is.....course, I guess it could be the ground as well?

Either way, what colors should I look for?

Thanks
