Turn Signal light in Dash

[adivin]

Ok, another turn signal oddity.  My hazards work and both arrows blink and light up in the dash.  My turn signals both work but the right side does not light up in the dash.  Any ideas?

The wiring diagram says that shouldn't happen as the power to that lamp comes directly off the wiring that powers the turn signal. It gets its ground from the gauge body. The stock '72 has 2 turn signal circuits - one for the front (GB & GR), one for the rear (WB & WR). The right turn signal pilot lamp is connected to the GB wiring to the front turn signal lamp. If the right front turn signal lamp is working, so should the pilot lamp. The hazard switch sends power through the same wiring...

That's IF everything is still stock - I've seen a LOT of under dash wiring that is NOT. Otherwise, oddity.

All wiring is stock.  The problem now seems intermittent.  Sometimes the right dash arrow will light, and sometimes it doesn't.  I have only been able to test the rear lights since I have no front fenders on the car at the moment.  So you're saying there is no way it could be related to the switch on the steering column?  What are you referring to as the gauge body?  The left side light seems to work consistently as does the hazards.

Oh, you should have said this in the beginning... 

You read what I said about the right turn signal pilot being tied to the right front turn signal lamp wiring? You have no idea if "your turn signals work" if you're only able to test the rear lights. I also said the turn signal lamps were on 2 separate circuits - one front, one rear.

In this case it certainly can be an issue with the right turn signal SWITCH. That is as a very common problem.
