TEST DESCRIPTIONSteps 1-8:
Steps 9-16:
Steps 17-26:
Steps 27-35:
The number(s) below refer to the step number(s) on the diagnostic table.
5. The specified values are from the A/C System Performance Test.
9. This checks for proper air temperature actuator movement.
10. The voltage will vary between 0.25-14.7 volts during normal operation. The HVAC control module connector must be connected during this step. This checks for proper operation of the air temperature actuator door control circuit and the HVAC control module.
13. The voltage will vary between 0.25-14.7 volts during normal operation. The HVAC control module connector must be connected during this step. This checks for proper operation of the air temperature actuator door control circuit and the HVAC control.
14. The auxiliary blower motor switch control circuit should not have continuity to ground when front auxiliary blower control switch is in any position except REAR CNTL.
16. The voltage will vary between 0.25-14.7 volts during normal operation. The auxiliary HVAC control module connector must be connected during this step. This checks for proper operation of the air temperature actuator door control circuit and the auxiliary HVAC control module.
20. This step checks complete auxiliary air temperature door control circuit from the HVAC control module to the auxiliary HVAC control module to the auxiliary air temperature actuator.
