## Discrepancy

FWD CABIN TEMP CONTROL ALMOST IMPOSSIBLE TO CONTROL.  CONSTANT COMPLAINTS.  SAMC TEXT:  NO HELP WITH HOT AIR SWITCH TURNED OFF.  BARELY MOVE CONTROLLERS WITH HOT AIR OFF AND STILL WAY UP AND DOWN AFTER PERIOD OF TIME.  PEOPLE ARE REALLY COMPLAINING.  OUTPUT NOW SHOWS 64F AND PEOPLE ARE SAYING ITS WAY TOO HOT...OPBLM - CLEAN THE CABIN TEMP SENSORS 22HK & 23HK AND BLOW OUT THE DUCTS PER MT 21-015.
