To replace the left air temperature actuator, one should begin with removal of the left side sound insulator, removal of knee bolster and Instrument Panel Module (IPM). Before you remove the actuator of air temperature, remove the retaining screws and disconnect the electrical connector from the air temperature actuator. For installation, place the new air temperature actuator and mount the driver air throughput retaining screws with a tightening stringency of 1.4 N.m (12 lb in). Replace the electrical connector back to actuator, re-install the IPM, knee bolster, and left side sound insulator. Finally, recalibrate the actuator.
