Brake and turn signal light not working.

Asked by May 17, 2018 at 09:14 AM about the 1993 Chevrolet C/K 1500 Silverado Stepside 4WD

Question type: Maintenance & Repair

I have replaced the circuit board in the taillight assembly on both sides, checked all fuses, replaced the brake pedal switch, replaced all the bulbs and everything is getting power correctly. My driver side turn signal and brake light do not work, but my running and reverse light work fine. Passenger side everything works correctly. I do have a heavy duty turn signal switch due to when I upgraded my taillights to LEDs and they were also blowing fuses so I took those out and have the stock taillights back in it and still having the same problem. With the LEDs, all my lights worked fine but it would blow the brake light fuse under the dash, even with the resistors on the taillight connectors. Been fighting this for years now, any help or advice?

The picture is fairly recent but has the stock taillights in it.
