Escape 4WD V6-181 3.0L DOHC VIN 1 Duratec (2003)
Control Assembly: Description and Operation
The climate control assembly has three system controls:
^
The A/C heater function selector switch combines a vacuum selector valve with two electrical switches to supply battery positive voltage (B+) to
the A/C clutch circuit and the blower motor control circuit.
^
The temperature selection is accomplished through cable-controlled positioning of the temperature blend door located in the heater core housing.
^
The blower motor switch controls the blower motor speed by adding or bypassing resistors in the heater blower motor switch resistor.
