    No Brake Lights, Blinkers flash really fast, fan blower motor clicks-

    Put the old obs harness back in the truck today. Got everything connected, and powered. But we ran into some issues. First the blinkers flash really fast when you use them...it acts like a tail light is out or something but the tail lights work fine. Second, The brake lights dont work at all. And Third, when you turn on the heat/blower motor, it clicks on and off and on and off repeatedley and the lights start flickering. What do you think is the issue? Grounds?

    Look like a grounds trouble but if I remember the tail light ground is screwed direct in the frame or bumper bracket.I`m pretty sure that your blinkers trouble is caused by your tail light problem.First step is to recheck all your fuse but I`m sure you have already check them and your heater seem to have power but not enough.Good luck! Thanks for sharing I read your thread everyday.I have a 1994 to.Your tuck is NICE!
