Tailights, nope, only headlights, 87 'Burb...

My wife noticed a burning smell, and next thing you know, My lower dash coutesy lamp goes ON with the headlights, off when dome lamp clicked on, and ONLY headlights for external lighting. No dash lights, tail, side, etc!
What the heck happenned? I'll try change the light swithch tomorrow, but havn't touched anything. My trailer harness was changed two weeks ago, I'll check it for a short. I HATE wiring! But I have a test lamp, and spare parts... Thx, Andrew

Happened to me before
, you have a short in the trailer wiring, your fuse blew up.
Change the fuse and the lights will come back but then find the short in the wiring, probably on what ever lighting you have to flat tow or right at the connection on your truck.
Last time that happened o me I blew 3 fuses and finally decided to unhook the light on the trailer at least I could keep my truck visible.

Found blown Fuse, will check wire, what else could it be??? So weird! Drove from Montreal, 60 miles, with foot tapping brake lights, sometimes!

Drive it with no trailer and see if the fuse blows again then the problem is in your trucks plug or the taill light wiring, if it doesn't then it's the trailer wiring.
