DESCRIPTION
The radio and navigation assembly controls the volume according to the MUTE signal from the television display assembly.
The MUTE signal is sent to reduce noise and a popping sound generated when switching the mode, etc.
If there is an open in the circuit, noise can be heard from the speakers when changing the sound source.
If there is a short in the circuit, even though the radio and navigation assembly is normal, no sound or only an extremely small sound can be produced.

Air Mix Damper Position Sensor Circuit (Passenger Side)
DESCRIPTION
This sensor detects the position of the air mix control servo motor (air mix
damper) and sends the
appropriate signals to the A/C amplifier. The position sensor is built in the
air mix control servo motor. The
position sensor's resistance changes as the air mix control servo m ...
