95 gmc 1500 door lock relay location

[acw]

Just joined this forum, this has probably been covered at some time, newbie here, my 95 gmc c1500 electric door locks and mirror control not working, windows up/ down work on left side only, I have replaced all door controls, windows, locks mirrors, door lock actuators, fuses that I can find. I read on some forums about a door lock relay, I have FOBs to lock & unlock doors, fobs work unlocking doors & locking doors.  I don't have power on orange wire going to door lock control. I think from diagrams I found that would be power wire. Anyone have any advise on what else to look for or how to trouble shoot my issue I would greatly appreciate the help. Any updated schematics or wiring diagrams would help also. I look forward to bring part of this site.
