## Discrepancy

ON TAXI-IN, WHEN ATTEMPTING TO OPEN A FOGGED-UP WINDOW WITH WINDSHIELD ANTI-FOG SELECTED ON, THE WINDOW JAMMED ON THE CAPT HEADSET CAUSING A SHORT. THE RESULT WAS A LOUD BUZZ AND A FIREBALL THAT QUICKLY EXTINGUISHED. THE CB Z-26 ALSO TRIPPED. MAINTENANCE PULLED C/B Z26 AND Z25 AND DISCONNECT WIRE FROM CAPT CLEARVIEW WINDOW. THE CAPT SLIDING WINDOW THERMOSWITCH HARNESS WAS REPLACED PER B717 AMM 30-42. TERMINATED HARNESS ENDS REF B717 WDM 3-42-01. OPERATIONAL CHECK WAS GOOD. BREAKERS STAYED IN. WIRING ON A/C SIDE CHECKED GOOD.
