The only time that my instrument lights and parking lights come on is when I hold the headlight switch in between parking and headlights. But that is just before headlights come on. as soon as I move the switch far enough for headlights then no instrument or parking lights. I took apart the headlight switch and cleaned up all of the internal contacts. Still works exactly the same. I don't think it is a ground issue as all of the instrument and parking lights do work as long as I hold the headlight switch in one very small spot between parking and headlights. Any Ideas? Do i bite the bullet and buy a $150 rebuilt switch? or is there something else in play here that I am missing?

confused I am about ready to put the parking and instrument lights on a toggle switch.

In theory, there is no difference between theory and practice. In practice, there is.
