As I said before, if the running lights work, the meters should have 12 VDC+. Of course, if the harness has been hacked, all bets are off. You could check the G/W wire to ground at each meter to verify.

You should do continuity checks on the R/L wire from the rheostat back to the meters. If you have a good ground and the R/L wire is intact to all of the meters, jumpering the R/L wire to ground should give you dash lights.

Sorry for the delay but just now getting back to the car and the dash. Since the weather has changed and driving season is here I have decided to put the dash back on without the lights being fixed. I will get back to it later. I do have at least one problem I need help with. I am not sure how the heater ductwork goes back together. I have included a picture of the duct part in question. Any help would be appreciated.

Thanks
