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.
