## Discrepancy

STRONG ELECTRICAL BURNING ODOR DURING DESCENT, JUST AFTER WINDSHIELD HEAT WAS TURNED ON. CREW DEACTIVATED WINDSHIELD HEAT, TURNED ECON OFF AND ISOLATED THE NR 1 PACK.  FUMES DISSAPATED.  CREW COULD HEAR MOTOR FAN THAT SOUNDED AS IF IT WAS BINDING.  FUMES SEEM STRONGEST AROUND C/B PANEL.  FOUND AVIONICS COOLING FAN NR 3 WITH C/B POPPED.  REPLACED FAN. FAN OPS NORMAL. C/B REMAINS CLOSED.
