## Discrepancy

DURING CLIMBOUT, PILOT SELECTED WINDSHIELD DEFOG.  ELECTRIC ODOR IN COCKPIT AND SMOKE SEEN FROM AREA BEHIND INSTRUMENT PANEL.  PILOT NOTICED THAT DEFOG BLOWER WAS NOT FUNCTIONAL.  CABIN PRESSURE WAS DUMPED AND ACFT RETURNED TO STATION.  INVESTIGATION REVEALED WINDSHIELD BLOWER MOTOR FAILURE.  R & R BLOWER MOTOR.  OPS CHECK OF SYS NORMAL.  GROUND RUNS SHOW NO SMOKE IN COCKPIT.
