## Discrepancy

WHILE ON GROUND, MASTER WARNING AND SMOKE LIGHT CAME ON, ENGINE WERE AT IDLE, APU ON.  NOTICED SMOKE AND FAINT ODOR COMING OUT FROM BETWEEN THE LAV DOOR POCKET AND RIGHT REAR OVERHEAD LIGHT.  PERFORMED ENGINE RUNS, WITH APU ON, COULD NOT SMELL SMOKE IN CABIN BUT HEAVY CONDENSATION COMING OUT OF WEMACS FLOOR VENTS AND SIDEWALL VENTS, CAUSING THE MASTER WARNING & SMOKE LIGHT TO COME ON FOR A SPLIT SECOND.  PLACED CLIMATE CONTROL IN FULL COLD POSITION TO FULL HOT, NO CONDENSATION, NO MASTER WARNING.  REMOVED COALESCER SOCKS FROM BOTH WATER SEPARATORS, CLEANED AND AIR DRIED THEN REINSTALLED.  PERFORMED A FUNCTIONAL CHECK OF CLIMATE CONTROL OPS CHECK GOOD, WORK PERFORMED IAW CESSNA650 MM CHAPTER 12-10-01.
