Does anyone have any experience with the cornering lights on a 86?

The left cornering light works correctly with the turn signals, but the right one does not light (bulb OK, no power at the connector and ground OK). The right turn signals work correctly.

Is the actual power switching done with the steering column mounted turn signal switch plate or through a relay?  If it is a relay, where is it hidden?

This circuit is not shown on my electrical diagram.

Thanks  Fred

I can't really answer your question, however, on my 88 I had a very similar problem. Changing out the light bulb corrected all. Bulb looked good, but I think the socket may have been the problem. Anyway, all is good now.

Hi Brian
I did check to make sure the bulb was good- have seen that problem before(bulb looked fine, but the filament was actually broken and sure enough it would move if you thumped it). 
Then I took a straight pin and probed into the wires before the connector- no power.
Lastly checked the hot wire to ground- no power and then the ground to known power and saw that the ground was good. 

That is why I think that the problem may be with a switch or relay. The other side works correctly.

Oh well, guess I will have to break down and get a service manual (after all these years) to see how this circuit is configured.  

Thanks for the reply

Fred
