First, you need to connect the electrical connector to the recirculation actuator, connect the I/P fuse and relay block upper electrical connectors, position the relay block and install the bolts and nut. Then, please connect the lower relay block electrical connectors and install the BCM and the HVAC programmer into the appropriate brackets. Finally, you should install the right sound insulator and the I/P compartment, and recalibrate the actuators.

First, you need to install the left air temperature actuator. Then, please connect the electrical connector to the left air temperature actuator. Finally, you should install the aspirator muffler, and the left-side sound insulator and recalibrate the actuators.

First, you need to align the mode door levers with the cam slots. Then, please install the mode actuator assembly and the left air temperature actuator. Finally, you should install the instrument panel assembly and recalibrate the actuators.
