John or anyone,
It would be helpful to know which terminal on the long connector into
the right side of the instrument cluster operates the turn signal. If
that's not getting 12 intermittently with the wipers, and the turn
signals are working, then the problem must be in the wiring between
the relay and the connector. If it is getting intermittent 12v with
the wipers, the problem must be either in the connector, the blue
foil or the LED itself.
Anyone know? Should I just trace down the blue-with-red to the
connector and test that?
We've had company in all week and though I've had time to change out
the instrument clusters (10 minutes) I haven't had time for the
troubleshooting.
Thanks,
Jim
