    At First I had no right side brake light. Changed the bulb still nothing. Took out the brake light switch. Brake lights work fine now. (Weird). Flashers work on both sides. No signal lights on either side. They dont even light up on the inside.

    Could this be a signal light switch or something else? :dizzy:

    Blown fuse or bad turn signal flasher unit. Could also be a bad turn signal switch itself. Its called a multifunction switch assembly. The fact that the flashers work says that the bulbs, bulb sockets, and wiring are all ok. So you must look into the turn signal circuit itself.

    on some trucks the 4 way flasher and the regular turn flasher are 2 different flashers. the regular turn signal flasher may be bad but the emergency (4 way) flasher may be fine.
    maybe you have some loose connections somewhere, that may explain the brake light switch, wiring problems can be hard to find at times just keep searching
