Quote: stu there is one position on the dimmer wheel just before you turn on the dome light that puts the dash lights on full bright , if you have that position then it's the dimmer switch , common problem 40yrs down the road .
The dimmer can be rolled through all the positions and not get the dash lights to come on at all. It will at the final stop get the dome light to work as it should.
I had the same problem with my other road runner years ago and it was the dimmer but that was with a corrored swith and this is with a newly rebuilt switch so am not thinking it's in there.
I have never replaced the HIGH BEAM switch but i can not understand how that would affect the dash lights??? Or does it come into play for that problem??
