I have a 2001 Lexus gs 300 and the driver side heater vents do not work. The passenger side vents work. Also when the air-cond is on both driver side and passeger side vents work. Its just when the heater is on

Check the air mix servomotor for the driver side, located at side of heater core housing, under dash.
