Drivers SIGNAL not working

if you have 1 indicator out and the other in its pair works flash unit and switch work
check the connector block for the column switch where the pulsing flasher signal is directed to left or right circuits.

in mine its is clipped to an upright in the dash just above the steering column

wires from the switch go to it and it feeds left and right front blinkers and left and right rear blinkers

i had a rear out and it was 1 dark green wire not making contact in the plastic 6 or 8 way connector.

i had no flash with test light at the connector behind the drivers side kick board

but i know the switch in the column worked due to test light at bulkhead and front indicator working.... so just followed wires from the back until i found a flash of the test light. which happens to be the distribution point i.e the connector for the column switch in the dash.

i knew the light housing was grounded becasue all other light functions worked and i could get the blinker bulb to light with 12 volt to the bulb base and the bulb shank pressed to the housing.
