Really need some guidance guys. Like I mentioned earlier, my D/S front window won't go up or down. All the other windows, door locks, mirror controls etc work fine. I bought a new window regulator assembly and installed it tonight. Same thing. Nothing. I checked fuses, relays. Wiring. I know it has to be something stupid now that the new regulator didn't work. Wiggled the door harness between the door jamb and door. Pulled and checked the switch assembly. Relays under the dash. Fuse box under the hood. Really getting frustrated but trying to stay level headed and think it out.

Really need help with troubleshooting, wiring diagrams and such so I can trace the issue down.

Got a volt meter? Start checking for voltage starting at the window motor, then the switch, then wherever the switch gets it's power from?

If you don't have a volt meter, harbor freight has em for cheap.
