are you working with a wiring diagram and a voltmeter or testlight?

OK, but you seem to be replacing everything. Before replacing the relay forinstance, did you use a testlight or voltmeter to check whether power was coming to the relay and whether when turning the highbeams on did the relay trip?
Have you tried unpluging the main connector at the BCM, checking it for any corosion and then reinserting it?

I found after opening up wire harness to dimmer switch the 3 wires..
Because Of Tilt Steering column and Lack of 1 more inch of Wire the little Purple wire was broke..
Well hopefully next person who has this problem finds this on Google...
Lol
