No voltage at blower when you hear the click? Have you checked the blower
door switch? i would think that would stop the whole thing, not just
the blower, but it's worth a check. Trace the wires from the blower back,
checking for voltage. Must be a relay on a board, if that has AC in,
no AC out when it clicks, you've found your problem.
