M812 Turn Signals

[armytruckdiesel]

Trucks turn signals do not operate for any lights. The turn signal indicator in the cab does not flash. What things should I be looking for to correct this problem? The headlights and brake lights work just fine.

Do you have the lights on while trying?? For some reason, maybe it's supposed to, but mine will not do anything unless my switch is on "Service Drive", then everything will work. Hope this helped.

Looks like to me either the turn signal lever is bad or the flasher unit has gone south.....cranetruck has had more experience with this so he might post a better answer and be able to tell you what to look for specifically....
