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. -- Andrew L.
