If your aircon blower does not work, strip it down to the printed circuit board. There is a Tyco 40 amp relay with a single soldered pin 5 on the 12v blower supply. The output of this relay goes to the rotary blower speed control switch. Mine had a dry joint from over heating due to a too small solder pad. The job took half a day, but saved a heap of money on a new aircon control unit.
