Been working on my project here lately and it has me stumped.
Tail lights work with lights on but brakes or turn signals dont.
3rd brake light comes on when you hit the brakes but the taillights dont.
Only my right front turnsignal works. but both bulbs come on with the driving lights Im thinking maybe the turnsignal switch is bad because when you click it to the left signal the dash light doesnt flash. but Im confused on the tail lights. ive checked all the bulbs and their good. Ive looked at the haynes wiring diagram and it doesnt make any sense to me. Anyone have a good wireing diagram i could take a look at?
 
I had similar issues with my truck when i bought it. Can't remember if it was exactly like yours, but it ended up being the wiring for the rear brakelight was melted together near the plug. Just throwing an idea out there..
