Actuator Malfunction



1. Ignition OFF, disconnect the X3 and X4 harness connector at the K33 HVAC Control Module.



2. Ignition ON, test for 80-200 ohm between the 12 V reference voltage circuit terminal 15 X3 and each control circuit terminal of the



appropriate actuator.



瀚慖f less than the specified range, test for the 12 V reference voltage circuit and the control circuit for a short circuit. If the circuits test



normal, replace the appropriate actuator.



瀚慖f greater than the specified range, test the 12 V reference voltage circuit and the control circuit for an open/high resistance. If the circuits



test normal, replace the appropriate actuator.



3. If all circuits test normal, replace the K33 HVAC Control Module
