If you are testing your wires with a high impedance meter (and measuring
voltages with it too) you may not catch circuits that no longer are
capable of carrying much current.

Is there 12v at the + side of the defroster?  try running a test light
with that 12v, to any ground, then the defroster ground.

ditto the 12v at the switch, and anywhere else along the way you can get
to it.
