## Discrepancy

DURING CLIMB,  BETWEEN 150 AND 170, CABIN AREA BECAME UNCOMFORTABLY WARM.   CREW NOTICED CABIN TEMPERATURE INDICATOR WAS INDICATING FULL HOT AND WOULD NOT MOVE IN AUTO MODE.  TEMPERATURE CONTROL WAS MOVED TO MANUAL AND TEMP INDICATOR MOVED TOWARDS COOL.  AFTER LANDING, TEMPERATURE CONTROL SYSTEM WAS LEFT IN MANUAL MODE AND CYCLED FROM HOT TO COLD SEVERAL TIMES. MANUAL MODE FUNCTIONS SEEMED NORMAL. ON INSPECTION, A PIN WAS FOUND PUSHED OUT OF THE CABIN TEMP CONTROL BOX CONNECTOR.  PIN REPLACED AND RESET INTO CONNECTOR, AUTO MODE WAS TESTED ON GROUND AND FOUND TO OPERATE NORMALLY.
