1. Check actuator motor
(1) Ignition "OFF".
(2) Disconnect DR Direction Actuator.
(3) Connect (+) terminal of battery to terminal 3 of DR Direction Actuator and (-) terminal to terminal 4
(4) Verify that the temperature actuator operates to the DEF position
(5) Verify that the temperature actuator operates to the VENT position with reverse connecting. ((+) to 4 and (-) to 3)




(6) Dose the actuator work properly ?





2. Check actuator potentiometer
(1) Ignition "ON".
(2) Connect DR Direction Actuator.
(3) Measure voltage between terminal "5" and "6" of DR Direction Actuator while operating the temp switch.
