## Discrepancy

DURING CLIMB, A STRONG BURNING ODOR EMITTED FROM THE CAPTAIN'S L1 LOWER LEFT WINDOW HEAT ELECTRICAL CONNECTIONS.  PLACED L1 IN OVERRIDE AND ODOR DISSIPATED.  AIRCRAFT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT.  REPLACED THE LEFT LOWER AND UPPER WINDOW HEAT TERMINALS ON L1 WINDOW AND REPLACED THE WINDOW HEAT CONTROLLER.  OPERATIONAL CHECK GOOD.
