Hey y'all, I'm a newbie here and glad I stumbled upon this board. I'd rather have joined without having to ask for help concerning a truck I'm troubleshooting, but I'm here so..here goes

It's a 96 GMC Sierra 1500. The turn signals and hazards are not working and when the brakes are applied both the front signals come on as well as the right turn indicator on dash. Push the hazard button and they'll go off, but still no signals or flashers.

I've replaced the rear circuit boards and the multifunction switch on column. Still have the same issue and troubleshooting is still leading me to the multifunction switch. Am I missing something? I've checked grounds front and rear and the one under left side of dash. Is there a ground I'm missing?

Thanks y'all! Look forward to talkin rides around here.

 

Have you checked your grounds?
It still sounds like an open circuit in the rear of the truck.

 

The ground on the left rear seems to be intact. I don't know of any others. I've removed the trailer harness too
