## Discrepancy

CREW REPORTED THAT ON DESCENT, WITH THE WINDSHIELD HEAT TURNED ON FOR ABOUT 10 MINUTES, A SLIGHT ELECTRICAL ODOR WAS PRESENT.  CREW FURTHER REPORTED THAT BOTH WINDSHIELDS WERE NOT HEATING.  WINDSHIELD HEAT WAS TURNED OFF AND THE ODOR DISSIPATED.  MAINTENANCE REPLACED THE WINDSHIELD HEAT PUSH BUTTON SWITCH ON THE FIRST OFFICERS SIDE.  OPS CHECKED GOOD WITH NO FURTHER DEFECTS NOTED.
