A/C AUTO AMP.
Description
INFOID:0000000003941321
COMPONENT DESCRIPTION
A/C Auto Amp. (Air Conditioner Automatic Amplifier)
The A/C auto amp. (1) has a built-in microcomputer that processes
information sent from various sensors needed for air conditioner
operation. The air mix door motors, the mode door motor, the intake
door motor, the blower motor and the compressor are then con-
trolled.
When the various switches and temperature control dial are oper-
ated, data is input to the A/C auto amp. from the A/C control.
Component Function Check

Press the AUTO switch, and then check that “AUTO” is shown on the display.
2.
Operate the temperature control dial (driver side). Check that the fan speed or outlet changes. (The dis-
charge air temperature or fan speed varies depending on the ambient temperature, in-vehicle tempera-
ture, and temperature setting.)
Does it operate normally?
YES
>> INSPECTION END
NO
>> Perform trouble diagnosis for the A/C system. Refer to
