If you have a bad signal switch do the indicator lights on the dash stay lit up ?? I heard it can also screw with your brake lights at the same time ? My signals don't work I replaced the flasher no dice the indicators on the dash left and right just stay lit I have a 69 f 250
Jacob Barkley if the brake lights work but no signals I’d suspect a bad flasher or a bad turn signal switch. I’d also check the junction of wires right under your rear bumper where the wiring branches off to the left and right tailights . Mine was a rats nest with broken wires and dirty connectors that had to be sorted out. On my setup there’s a ground on the flasher unit that needed to be secured properly and the taillights themselves are grounded by screwing them into the bed of the truck. I had to strip away the paint on the little tabs which the tail lights screwed into before they worked properly.
@@kevinpyle9479 What's it to you anyway if I did or didn't, you Spelling Patrol or what? You have to be born with no common sense to be so hypocritical.
