Thanks for the reply, I looked at the diagram that you mentioned and it's not like that at all.....only one wire from the dash right to the defogger motor and only one connector at the defogger motor, so that all lines up, btw, both the wire and defog motor (are) original to the car.... it's just after 40 years of restoration I don't recall having felt (2) clicks of the switch but only one motor speed....still confused , but at least it works.
Later, BUZZ
1st: are there 2 wires going to the switch?
2nd: Does it the motor work when using switch in both positions.
Note: some years/models they used a "resistance" wire in-leau of a resistor.
That's how it would reduce the speed.
