Description
INFOID:0000000005514618
COMPONENT DESCRIPTION
Air Mix Door Motor (Driver Side)
• The air mix door motor (driver side) (1) are attached to the heater
& cooling unit assembly.
• It rotates so that the air mix door is opened or closed to a position
set by the A/C auto amp.
• Motor rotation is then conveyed through a shaft and the air mix
door position feedback is then sent to the A/C auto amp. by PBR
built-in air mix door motor.
