M923A2 Turn Signals and Brake Lights

[Navo]

I have been driving around and haven't had any issues. Until the other day, when you put the switch in the brake light mode (one turn to the right) the turn signals do not work. The light comes on at the indicator when u pull or push for the signal but nothing happens. Also the brake lights don't work at the rear of the truck. If u go to the second position for the headlights and parking lights they seem to work but no brake lights or turn signals. Anyone have thoughts on this?

Yes Sir, the bulbs look fine. It just stared acting this way. When I move the turn signal to a position the light stays solid green. I'm thinking the the switch that controls all the lights.

If the switch stays solid green you might have a bad control module or a bad connection somewhere. You need to manually check all the Packard connections and then test each bulb and go from there.

Bad control module

Sounds like 2 issues.

stoplight switch on the inside of the frame rail by the tank is suspect for brake lights especially if the running lights come on but no brake.

Turn signal assembly sounds like issue #2. Many members have reported sticking contacts recently in those units. Several folks have opened them up, cleaned the contacts, and reported success.

Sounds like its time to upgrade to the hmmwv verson so you can make it self cancel
