A/C Refrigerant System, Switches, Sensors And Valve Connections


NOTE:
- As a running change in production, pressure switch -F129 is replaced by high pressure sensor -G65-.
- The function of Coolant Fan Control (FC) Module -J293 and vehicle wiring layout will vary depending on whether vehicle is equipped with A/C pressure switch -F129- or high pressure sensor -G65-.


A/C Pressure Switch -F129-







A/C clutch -N25- is disengaged when -F129- detects insufficient or excessive refrigerant system pressures (A/C compressor protection).
The coolant fan(s) -V7- are also switched to speed 2 when -F129- detects an increase in refrigerant system pressure.
