a few days ago my horn just came on in the driveway.I didn't have time to deal with it so I just disconected it. now my light switch is acting funny. this morning my low beams didn't work,but highbeams did. now tonight neather work. if I hold the swich back the beams come on,but when I let go they go off. any Ideas?

Electrical gremlins..... I would start by chasing some of the wires related to those items and look for a short somewhere. Sorry I can't be of more help.

 

I put in a new multi-function switch and the light problem went away, still have the horn problem.
unrelated question: Does anyone know if I have a cmt on this truck? haynes doesn't list one that I can find
