My brother has an 06 Ranger and it recently started blowing the fuse for the dash lights. Shortly after tail lights quit working, I did some digging and found that the fuse that runs the tail lights is also blown. I took the dimmer switch out but I'm wondering if it would be the actually headlight switch causing problems. Or is there a way to test these switches out of the truck before I send him to get new switches?
I checked and couldn't see anywhere the wiring is damaged between the switch and the rear end of the truck.
