2005 Chevrolet Equinox Parts Questions & Experts Answers

• Q: How to replace the defroster Blend Door Actuator and calibrate the HVAC control module on 2005 Chevrolet Equinox?

  A: Begin replacement of the defroster actuator by discharging the communication interface module but only when present before removing the electrical connection from the defroster actuator. Start by removing defroster actuator screws installed in the hvac module to extract the defroster actuator. Align the defroster actuator with the defroster door shaft while you rotate it into position before screwing the defroster actuator screws to the hvac module with a tightness of 1 n.m (9 lb in). Drive the electrical connection to the defroster actuator before reinstalling the communication interface module when equipped. To calibrate the mode actuators push the a/c and recirc buttons of the HVAC Control Module three times each within two seconds of the first push. The calibration process takes 10-30 seconds based on battery voltage while the a/c and recirc button leds will flash continuously until the system completes calibration. Verify proper operation after completing ignition cycling. Proper air distribution depends on the successful calibration of the HVAC Control Module whenever a mode actuator or HVAC Control Module has been replaced.
