77 F100 Electrical Problem

I have a 77 F100 Ranger Pickup and am having an electrical problem. My turn signal lights and flasher works when the lights are off. When I turn on my lights (without the turn signals) the right (passenger) turn signal indicator on the instrument panel lights up. When I turn the left blinker on with the lights, it works fine, but the right does not. I am sure it is a grounding problem, but don't know where to start... I have replaced the headlight switch, but that did not fix the problem... Can anyone point me in the right direction (hehe)?

Easy one !

Grounding problem in either the front TS light socket or Rear TS light socket of the Indicator side that is illuminating.

Clean everything up inside the sockets and to ground.
