Mode/Air Mix Problems After Control Panel Replacement

APPLIES TO:
2003-04 Accord

SERVICE TIP:
If you have heater mode motor that chatters and the air mix motor and outlet temperature only adjusts to HOT or COLD, check if the heater control panel has been replaced. If a heater control panel for a 2-door model is installed in a 4-door model, you'll get these symptoms.
