68 GTO blower motor switch
 

Before I spring for a $76 blower motor switch is there anything I should know about potentially repairing the original?

On the surface it appears pretty good, looking inside it doesn't look horrible, it operates nicely at the lever. But I get no continuity in any position between any of the contacts. They are very simple sliding contact switches ... hard to believe every contact inside has failed.

Is there some kind of testing procedure I'm missing. I even tried using the body of the switch as a contact point.

I was able to rebuild the reed switches on the AC controls but can't get this blower motor switch to do anything.

Are the repop switches any good?

Thanks.

Should I move this to the electrical section?
