Fuse 15 directly feeds the following Cooling/Aircon relays:
1. K60(Relay - Compressor, Aircon) which controls K87(Relay - Blower, radiator) and controls M4(Motor - Blower, radiator).
2. K52(Relay - Blower, radiator) controls M11(Motor - Blower, radiator) and is fed from M4.
3. K28(Relay - Blower, radiator) controls M11.
4. K48(Relay - Blower, relay box) feeds M28(Motor - Blower, relay box) and is switched by K26(Relay - Blower, radiator).
5. K67(Relay - Blower, radiator) feeds M12(Motor- Blower, radiator).
6. K22(Relay - Pump, coolant) controls M54(Motor - Pump, coolant on the radiator).
K60 also feeds S128(Switch - Temperature, coolant on the radiator) which energises K52 and K28.
K26 feeds S88(Switch - Temperature, coolant on the radiator) which energises K48 and K67. It also provides power to M54.
S20(Switch - pressure on the aircon plumbing) has three parts: S20.1(Switch - Compressor, low pressure), S20.2(Switch - Compressor, high pressure), S20.3(Switch - Revolution, acceleration). S20.3 has a diode connection from both K28 and K48.
M4 and M11 are the front fans, M12 is the main fan.
