turn signal goes solid when hitting the brake

[broncobuckinaround]

checked it out the best I could. I have some clues to what it could be but I'm not sure.

when driving I'll signal to turn and left or right will blink fine until I hit the brake. then go solid.
also when they are blinking all the lights in the back are too.

usually a light is burned out....check them all. that or a short in the trailer wiring.

the wrong blinker relay can do it too.....or led lights

You likely have a bad ground for the rear lamps. Less likely, but still possible, is frayed wires that are making contact with each other.

+1 ^^^

Also if you have Trailer wiring it can short out causing that

Ok I'll check it out more. Maybe I'll just remove the trailer wiring

Found the trailer wiring was smashed by the hitch. Don't know how I missed it. But the lights are working normal for now. I'll post back in a few days to confirm the fix.

Thx for the help.
