TL L5-2451cc 2.5L SOHC MFI (1997)
Control Assembly: Description and Operation
The climate control unit receives battery voltage at all times through fuse 39. With the ignition switch in ON (II), voltage is supplied to the climate
control unit and the water valve control solenoid valve. The control unit is grounded at G404.
The climate control unit controls the air delivery motors, and supplies a 5V DC reference voltage to the air mixture control motor.
The air mixture and mode control motors each receive inputs from the climate control unit. The air mix motor regulates the mixture of cold and hot air
by varying the position of the heater-evaporator door.
The mode control motor controls the direction and volume of outlet air. The air flow can be directed to the dashboard vents or the corner vents.
Both the air mixture control motor and mode control motor are grounded by the climate control unit.
The recirculation control motor receives battery voltage through fuse 7 when the ignition switch is in ON (II). It regulates the position of the fresh/recirc
door, and is controlled by two position inputs from the climate control unit ("Recirc" and "Fresh").
