I'm getting close on this. I swear the widows and locks have been the biggest pain of this rebuild!
I replaced the Suburban harness with a truck harness and that fixed most of my problems. I figured out the lock relays apparently need to be screwed to the body for a ground, because I screwed the bracket down and the locks started working. I also had to replace both lock switches. I had a mess of old switches but none of them worked in both directions. I guess after 30 years they wear out.
My last problem is the passenger side window switch. It only works in one direction. Sometimes it only moves the window up, other times it only moves the window down. It's not the switch. I have a new switch, and several used switches and they all behave the same way. Any one have any ideas? I figure I must have a bad wire somewhere, but I'm not sure how to test it.
