Toyota RAV4 (XA40) 2013-2018 Service Manual: Compressor solenoid circuit (2006/01- )
Description
In this circuit, the compressor receives a refrigerant compression demand signal from the air conditioning amplifier. Based on this signal, the compressor changes the degree of refrigerant compression.
Hint:
*: Compressor and pulley for 2az-fe, compressor and magnetic clutch for 2gr-fe
