  Q: How to replace the LH Blend Door Actuator on Buick Park Avenue?

  A:

  Start by removing the left side sound insulator followed by the aspirator Muffler to replace the left air temperature actuator. First disconnect the electrical connector from the left air temperature actuator while you remove its retaining screws before removing the actuator itself. Position the new left air temperature actuator in its designated location then fasten it with retaining screws while applying 1.4 n.m of torque to the screws (12 lb in). Reinstall the remaining components as follows - reconnect the electrical connector to the actuator and reinstall both the aspirator Muffler and left side sound insulator. Complete the actuator calibration when needed.

  Q: How to service the RH Blend Door Actuator on Buick Park Avenue?

  A:

  Servicing the right air temperature actuator starts with sound insulator removal then moving onto the ip compartment. Start by removing the Body Control Module alongside the hvac programmer from their brackets before placing them aside. First remove the actuator's retaining screws then disconnect its electrical connector before extracting the actuator. Installation requires proper placement and securing of the right air temperature actuator by means of retaining screws which need to be tightened to 1.4 n.m (12 lb in) following the fastener notice in service precautions. The vehicle requires a right air temperature actuator electric connector reattachment. Body Control Module and hvac programmer bracket installation follows with subsequent ip compartment and right sound insulator replacement. Finally, recalibrate the actuators.
