Hi all,

I am having some trouble with my turn signals, they work fine until I hit the brake pedal. Once I hit the brake pedal, they stop flashing, just come on solid. As long as I dont hit the brake pedal, they work as they should. This happens on both sides. Doesnt matter if there is a trailer hooked up or not.

All bulbs, fuses, wiring are good, have checked it all out. I am thinking either brake light switch or turn signal switch is bad, any ideas? Thanks.

 

It wasnt the turn signal switch.

 

Put your parking lights or headlights on and try them. It sounds like a bad ground, and they could appear to be working by going to ground through the park/tail lights when they are off. If they don't light with the park/tails on there is a bad ground at the rear lights.

 

Found the issue. Apparently a previous owner had some extra lights wired into the system...some side marker lights or something. I found a big tape job under the drivers side, with a bunch of cut and spliced wires, and the left and right turn signal wires had actually corroded together and shorted. Repaired all the wiring with heatshrink and problem solved.

 

check your turn signal fuild it might be low
haha lol

 

Damn! It only took you 7 months to figure it out.
