    So I had it out for the second time this year to get more exhaust work done & noticed my dash wasn't showing my signals on so I got home and checked it all out.. Running lights & headlights all work, the blinkers and brake lights don't.. Where should I start looking? I'm extremely sick right now and figured I'd save myself some of the battle and ask here first before I spent hours searching... Thanks in advance...

    Blinkers and brake lights both run through the turn signal switch, you could also have both of the bulbs in the back for the brake /turn signal filament burnt out I would check the bulbs first then the turn signal switch.

    Turn signal switches are notorious for going bad and causing this exact symptom, no easy way to check without taking steering wheel off and using test light on contacts.

    It is not a fuse because turn signals and brake lights are integral with headlight switch and you have headlights and marker lights.

    Hope this helps

    Sometimes clicking the hazard switch back and forth a few times will cure this! Do the hazard lights work? As was suggested, the turn signal switch may be kaput. :)

    X2 on the turn signal switch. I chased a similar problem and it didn't get fixed until I replaced the whole switch including the attached wiring harness.

    Hazards work.. The turn switch does look really worn I'll go rose a new one right now an see if I can get it here today.

    I put a test light on the contacts inside and they all have power when hazards are on so it's making contact... Do the hazards and blinkers use a different flasher or both the same?

    Will be a different flasher for hazards as they must be able to flash all four corners without being damaged, std R/L blinkers wont last in this duty...

    Your problem won't likely be the std flasher or the brake lights would still be working... Usually issue is a broken wire within the switch that feeds power to the R/L signal portion... The wire must flex each time the signals are used, eventually it breaks(usually inside the plastic covering)...

    Changed the flasher because they didn't have the switch in stock.. Blinkers work now... Now I just don't have any brake lights.. (I've replaced that flasher like every 3 months now)

    Switch on brake pedal also sends voltage to the signal switch which passes it on to both lamps assuming R or L isn't selected... First thing would be to verify voltage to & from pedal switch...
