found out I have no brake lights, both are out. Fuse is good, and I put in a brand new relay. Still no joy.
I also noted that stepping on the brake does NOT deactivate cruise control.
I was troubleshooting more today and when I stepped on brake the lights came on, as they should. But only once. I suspect one or both of the switches on the air brake need to be replaced. Looks like a very simple fix but does anyone have part numbers or another idea?
