My tail lights, break lights, and lisence plat lights will not work, but if i trun off my lights and use the blinker it will blink very slowly like every 5 secs or 7 and if the lights are on the blinker wont work at all, when i have the lights off the hazzard lights will work but if the lights are on they wont. it did this a few months ago for about a week or so but i cant rem if i did anythign to fix it and it was working good until now. PLEASE HELP, ive already put 1000 into this truck and im running out of money to put in it help.

 

I would say to start out check all your grounds with a test light as that wont cost anything but time. Then after that go over your power wires, relays, etc. Hopefully its something silly like a loose or corroded wire and its an easy fix

 

i had the same problem i replaced the relay behind the glovebox and it worked for me try it its cheap for a relay

 

yeah it sounds like a rely problem to me as well....
