Blinkers going crazy lights on dash dim when you brake turn right

The problem was a bad left front blinker socket that was grounding out

Check your third brake light

The signal wire going to the right front has a splice for the dash indicator, a wire branching off from the turn wire and going to the dash. It sounds like that right signal wire is broken or lost a connection before it splices off to the dash, so the problem sounds like it is under the dash, either coming out of the turn signal switch to the flasher or from the flasher to that splice. You may need a multi-meter to check voltages on that wire at various places under the dash. Ascertain which color wire you need to concentrate on. Check for voltage on it with key on and right blinker on-voltmeter will spike to battery voltage, then fall to zero as the flasher breaks voltage continuously, if checked after the flasher. If checked when leaving the turn switch, it should be a continuous signal on that wire. Think you better find a wiring diagram to find the right wire to check. Good luck.

You may have a bad relay that is causing your problem. Have you done any diagnosis to this circuit ? Can you share the original problem ? How did it begin ? What have you done so far to correct this problem ?

check for a bad ground wire for the tail lights. You are looking for a black ground wire near the bottom of the left rear corner of the car, inside. you may need to take the trim panel off to find it. if you take out the left tail light you should be able to follow the harness to where the black wires come out and a terminal is screwed to the body. turn on the hazard lights and when you get near the problem the lights will brighten and dim.

bad bulb on right side check and replace

The right blinker issue sounds like you have one bulb out either front or rear check them both. The left blinker issue sounds like either bulbs(both out) or fuse, or worst case blinker switch has gone bad on left turn only so not picking up the signal.

you have a ground fault somewhere, try cleaning all the ground leads look for corrosion and rust.

probably needs a turn signal switch

Pull the bulb out of both left side turn signals and check the filaments. As these are double filament bulbs, sometimes the filaments break and lay across the other creating a feedback issue.
