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
