What was found
CREW INDICATED AN UNUSIAL ODOR FROM THE AC VENT. DEACTIVATED THE AC, SCENT WENT AWAY, PROCEDED TO HANGAR. TODAY ON ACSN: 54392 AN ABNORMAL ODOR WAS DETECTED WHILE THE AIR CONDITIONING SYSTEM BLOWERS WERE OPERATING. I TRACED THE SMELL TO ONLY BE COMING FROM THE AFT CABIN VENTS AND COULD HEAR THE AFT BLOWER MOTOR WASN'T OPERATING CORRECTLY. THE WIRING/CONNECTORS SHOWED NO SIGNED OF OVERHEATING, R&R'D AFT BLOWER MOTOR AND PERFORMED OPS CHECK. EVERYTHING SOUNDED AND SMELLED NORMAL.
