I replaced my turn signal cam and fuse last night and my blinkers still won't work. What else should I look for?
Do you

Check turn sig switch and grounds on rear of truck tailights. Make sure all your bulbs are good as well.

I pulled the switch out and cleaned the contacts and replaced all the bulbs. Still nothing and the hazards don't turn on either. The harness for the rear drivers side light has a blue wire spliced to the yellow wire and is attached to the truck body.

When I turn the truck on and hit the light switch, all the proper lights turn n. The hazards and flashers will not work. I'm ready to take a sledgehammer to this thing.

There are two flashers for this vehicle one for hazards and one for signals. Check both, and make sure power I going to theflasher. The key has to beon for the turn sigs to work.

I tried using them both with the truck on and off but get nothing. I've replaced the signal flasher but not the hazard flasher. I looked it up and the signal flasher was a cube and the hazard flasher was a cylinder.

You'll have to check for power you could have a bad turnsignal switch as well

With a volt meter or test light. If it gets power in and not out then it's the switch but if it puts power out then you have another problem like a shorted wire, etc.

I ripped it all apart and found that the wiring for the hazard flasher was fried. I had to replace the flasher and splice the wiring. It all works now. Thank you so much for the help. I will leave a donation when I get some money. Haven't worked for 2 months. Have a great night!
