I have a 2017 Sierra 1500 with factory rear slider with defrost. Last winter it quit working. There Is power to the braided wire soldered to window on D. side and across all of the grids on that d. Side section. There is good ground from the soldered wire from p. Side to the d. Side soldered wire. I have no power to the p. Side or middle section and for the life of me can not find where power goes from the d. Side to the other sections (where do I test). The tabbed connections appear just to connect current between the center and p.side but where does power get to these sides. Having difficulty finding any info on where to test next to see why it is not working. Fuses good and relay has been swapped with GM Recall being done shortly before window quit working.

Just pulled off "A Pillar" cover and wet from top to bottom, also noticed a small stain on headliner in corner. Removed shark fin and sealed around the hole and reinstalled.

Rained all day today, parked in driveway. Entered truck and noticed some water on weather tech mat below e-brake and pad on ebrake was wet. Felt up under lip of bottom of dash just above e-brake and it was wet. As soon as I drove away a small amount of water ran from under dash in that spot and onto the mat as I accelerated and turned. What would be most logical cause for this??? WINDSHIELD? Sunroof Drain? Any ideas that are quite common. Never noticed this in the past until today. Once rain stops will try to investigate further but may be tough to see directly. 2017 Sierra Denali 1500
