Refrigerant Control Solenoid Valve: Description and Operation

When the Compressor Clutch (K107) is engaged, battery voltage is applied to the Rear A/C Water Valve (K207). Ground is provided through the closed switch contacts of the Passenger's Rear Fan Speed Switch (X246), Rear A/C Fan Speed Relay (K205), and the Rear A/C Evaporator Temperature Switch (X260). The Rear A/C Water Valve (K207) is then controlled by the status of the Rear A/C Evaporator Temperature Switch (X260).
