My mirror problem is solved.

First the wires were all broken between the drivers door and the
dash.  I replaced them.  I tested the passenger door wires to the
connector behind the glovebox...luckily they were all good.

I thought it was the switch, even tried a couple of different switches.

It turns out the brown (ground) wire going to the SWITCH connector
was not making contact with the switch.  A few jiggles in the
connector contacts with a pointing tool fixed it.  I guess the brown
wire is used for the mirror motors, but not the clutch since my
mirror clutches worked.

Thanks to Marco from The BusLab for helping troubleshoot and repair it...
