When I turn on the headlights the fuse blows and I no longer have headlight or tail lights but the brake lights and turn signal still work. I even took out the bulbs and it still blows the fuse
On my 1997 Sonoma when I turn on the headlights it blows the fuse and I even lose my
tail lights but my brake light and turn signal still work. I took out all the bulbs and it still
blows the fuse
The first thing to check is see if it has a trailer plug, repair wiring there if a problem is found, if it is good then start to check all of the lighting grounds, make sure they are clean and tight, if you haven't found the problem by now then you will need a wiring diagram to show you the power pathways and wiring colors so you can trace out each lighting circuit.
I went threw that battle last year, chasing wires changing fuses, thinking it was a bad relay pulling my hair out. You know what it was, the freaking head light switch on your dash! You can pull one out of a wreckers and try it or just buy a new one. It is for sure your headlight switch.
