headlamp switch
is there a way of testing a headlamp switch? I have a 89 f-150 i opened the door the other night and my interior light didnt come on , so i started the truck put the head lights on and turned the **** to turn on my interior light on and bam heared a pop no dash board lights. I replaced the fuse still no lights as soon as i turn the head light know out goes the fuse. I am thinking that my switch is bad?? any thoughts or ideas
Thanks

You could test it wth a multimeter if you have a manual that tells you what each terminal is on the switch. Personally, I would just go get a new switch. Ford has used that same switch for many years and they do go bad pretty often. I just replaced mine about a month ago. I got mine at Napa for about $12

ok replaced the switch and no luck. the old was bad it was all ucked up and the spring on the resistor wasnt conected. so i ran a power wire to the spot on the switch for the lights and it would light up, but the wire got super hot,s o is there a relay or fuse link for the dash lights? i checked all the fuses, one other thing i installed a radio last weekend, and the lights on the radio stay lite all the time it does not dim dowm, could this have something to do with it. I used a wiring harness so i know no wires are mixed up
thanks
