What did I find but a full set of coach keys for every lock system. Nice little surprise.
As for the brake lights/cruise not working, my Cummins mechanic says it actually may be the air brake release button that's pressed when shifting to drive. Interesting.
If your coach is diesel and on a Freightliner chassis, your brake switches (2) will be on the bottom side of the brake treadle. To see them, you have to be under the coach. Several folks have had corrosion/ dirt on the terminals causing the cruise control to be inop. I've just had one of the switches fail in the on position, making the cruise inop but the brake lights were on also.
I don't know what the mechanic is referencing about air brake release button, unless it's the big yellow knob (parking brake release) and I don't think it has anything to do with the cruise control.
If all else fails, call the Freightliner help desk.
