Spent good part of yesterday trying to figure out why the high beams wouldn't work, will have to tackle it again today. Using schematics, found the wire that if we ground it, lights do come on, so no issue there. Read through the theory of operation on Alldata and tried to work through the circuit diagram, but the write up is not detailed enough to walk you through how all the various sections come into play.
Had spare parts from another known good donor and switched out parts as a hail mary but got nada. Switched out the dimmer switch, left hand fuse block (with the headlamp relay wonderfully located on the inside of it...really engineers?!?).
