Turn Signal problem

[deathlinx]

ok this might be hard to follow but i will do my best.

1969 C10 396

ok turn signal lights and indicators work normal with headlights off, if i turn on my headlights my RH indicator light in the cluster comes on and stays on, therefore my right turn signal does not work i push up on rod and it does nothing, no flshing of indicator or light or even the fuse flasher, the left side continues to work as normal, turn the lights off and its all normal again.

i put in new headlight switch same thing happened, new bulbs, cleaned the connections, took the flappy wire thing off the cluster and cleaned it...im very baffled of what is happening.

if there is anyone that may be able to help it would be a great day!
