Problem finding electrical short

The headlight dimmer switch switches the headlight power between high and lo beams. It also mounted on floor, sometimes it fails, and a short to ground happens. As a second check, disconnect the switch 3 wire cable and see if short goes away.
Thanks for the reply KitCarlson.
This was one of the first things I tried as I removed each connector from the harness to locate the short.
Thanks again and please let me know if you think of anything else. This is a weird one for sure!!
