Temperature Door Actuator

In order to replace the left side air temperature actuator, you must first unfasten the I/P carrier and remove the retaining screws that hold the actuator in place and disconnect the electrical connector for the actuator and pulling out the actuator itself. For installation, place the new left side air temperature actuator and fasten it by retaining screws and tighten them to 1.9Nm (17 lb in). Reconnect the electrical connector to the actuator's and reinstall the I/P carrier. If automatic climate control (C68) is available on the vehicle, perform the actuator calibration for air temperature afterward.

Firstly, after removing the ip compartment and the right sound insulator, it's possible to replace the air inlet actuator. Then, disconnect the Body Control Module and the hvac programmer from brackets and remove them from their brackets and bear them aside. Pull low electrical connectors off the i/p relay and junction block, unscrew bolts and nuts, rotate the relay block, then pull off the upper electrical connectors. After that, remove i/p fuse and relay junction block and remove air inlet actuator electrical connector. The air inlet actuator retaining screws should be also removed and the air inlet actuator itself. For installation, first loosen the retaining screws to the separating position as the new air inlet actuator is installed, then tighten it to 1.4 n.m (12 lb in). Retreat the electrical connector from the air inlet actuator, and attach the upper electrical connectors of the i/p fuse as well as relay block. Position the relay block and tighten it with bolts and nut at a torque of 8 n.m (80 lb in). Reconnect the lower relay block electrical connectors, re-install the Body Control Module and the hvac programmer to hang in their holders, install the right sound insulator again, and lastly, the ip compartment back.

The process starts with instrument panel (IP) upper trim panel removal followed by IP lower trim panel removal and glove box assembly removal. Start by taking out the passenger side air bag and disconnecting the electrical connection from the air inlet actuator . The actuator removal begins with screw removal from the air inlet and concludes with extracting the actuator itself. Install the new air inlet actuator into position then fasten it via retaining screws until they reach 1.6 N.m (14 lb in). Reinstall the passenger side air bag later followed by the IP lower trim panel and glove box assembly before securing everything with the IP upper trim panel. Finish by connecting the electrical connector on the air inlet actuator. The inspection procedure should confirm that all systems are functioning correctly.

To replace the Actuator Air Temperature, start by disabling the upper trim panel and the defroster duct. Next, remove the 3 air temperature actuator screws and disconnect the air temperature actuator's electronic connector before removing the actuator off the vehicle. To install, hook the air temperature actuator to the electrical connector and mount the actuator. Make sure that you install the screws to the air temperature actuator and tighten at 1.9 N.m (17 lb in). Lastly, put back the defroster duct and the upper trim panel.

To replace the left air temp actuator, first remove the right in sound insulation, then park brake pedal assembly. Pull off the electrical connector that serves as the connection between the driver air mix actuator and the actuator itself plus remove. Start by installing the driver air mix actuator, making sure that you move in a manner that follows the Fastener Notice in service precautions. Tighten the driver air mix retaining fasteners to the quantity of 1.4 N.m (12 lb in). Next is to reconnect the electrical connector to the driver air mix actuator, to reinstall the park brake pedal assembly, then to reinstall the right sound insulator. Lastly, recalibrate the actuators as per the BCM Programming/RPO Configuration (DIM), BCM Programming/RPO Configuration (IPM), and BCM Programming/RPO Configuration (RIM) from the Body Controls System.

In order to service and fix the defroster actuator, start by the elimination of the IP carrier. Next is the removal of screws on the defroster actuator and the electrical connector that is attached to it. After you remove the screws, pull out the defroster actuator. First, for installation, place the new defroster actuator in its place while adhering to the Fastener Notice of the Service Precautions. Fasten the actuator using screws and tighten them to 1.9 N.m (17 lb in). After doing this, reconnect the electrical connector to the defroster actuator and the lastly, reinstall the IP carrier.
