Brake lights won't work

[Rick Jeep]

I have an 1986 Jeep Comanche with no brake lights. Old switch blew and I replaced it. Still no break lights. No Blown fuses all running lights work and all turn signals lights work. Any ideas?

Remove all the bulbs and check the contacts. Try reinstalling them one at a time and keep testing your lights.
 

Also, lets see if @Pete M can move this to the modifications and repairs section.

sorry I didn't spot it earlier.

Do the Hazards work? If not, double check the hazard/stop fuse.

I'd check around the back portion of your harness that connects tail to tail and plate light/hitch harness(if you have one). A short or ground out there could potentially cause just the brakes light to go out on a poor slice or bad connection.

Mine did this randomly for a bit, turned out to be a corroded brake/hazard fuse and dirty fuse socket, check this out closely.
