The switch is a common failure (BTDT * 2), since *all* of the
power of the defroster goes through the contacts; there is no relay.
However, since there is 12V at the wires, the switch is doing it's
job. It could be that the wires are dying. There is a "paint" out
that conducts for repairing these beasts. A quick trip to Auto
Palace (or wherever) should do the job for $3.
