OK SO WE HAVE A HMMWV, M1165, THAT HAS A L/R TAIL LIGHT THAT DOESNT BLINK. OK I KNOW WHAT YOUR THINKING: CHECK THE LIGHT BULB, IS IT GETTING VOLTAGE, DID YOU CHECK THE HOUSING? WELL YES, WE DID. ITS GETTING 23.4 VOLTS, ITS A NEW HOUSING, THE ELECTRICITY IS PULSING. SO WE CHECKED THE CONNECTION. PLUGGED THE RUN LIGHT INTO THE BLINKER LIGHT AND IT WORKS. PLUG THE BLINKER INTO ANY OTHER LIGHT AND IT WORKS. JUST NOT THE BULB ITS SUPPOSED TO.

TRUCK SEEMS TO BE WELL ON ITS WAY TO BECOMING OUR NEW "DEVIL TRUCK" IF WE CANT FIGURE THIS OUT SOON...

Flasher relay? back in the day we had a truck that was similar. It turned out to be just one of the pins on the flasher relay. Just a shot in the dark.

WELL IF I PLUG THE BLINKER INTO LETS SAY THE BLACKOUT LIGHT AT THE HOUSING, IT BLINKS.

uhm.... well that is strange. did you switch housing units? left to right... see if the problem follows the house or stays in place.

WE PUT A COMPLETELLY NEW HOUSING IN BUT I WILL TRY AND SEE IF IT FOLLOWS FROM LEFT TO RIGHT.

We just had a M1165 do the exact same thing but with the R/R turn/brake light. It ended up being the turn signal switch.

I HAD NO LUCK FIXING IT BUT I WILL TRY THE FLASHER SWITCH. THANKS EVERYONE!!

yea it ended up being the turn signal switch. good call.
