3. Pull the lower edge of the upper finish panel away from the instrument panel. It is best to grasp the finish panel from the lower LH corner and pull the panel away by walking hands around the panel in a clockwise direction.
4. Remove the four Torx head screws retaining the control head. Pull the control head away from the instrument panel into a position that provides access to the rear connectors.
5. Disconnect the two harness connectors from the control assembly by depressing the latches at the top of the connectors and pulling.
6. Remove the two nuts retaining the vacuum harness. Pull the control assembly away from the instrument panel.
INSTALLATION
1. Connect the two harness connectors to the control assembly. Push the keyed connectors in until a click is heard.
2. Attach the vacuum harness to the vacuum port assembly. Secure the harness by tightening the two nuts.
3. Position the control assembly into the instrument panel opening and install the four retaining Torx head screws. Ensure that, as the control is positioned, the locating posts are correctly aligned with their respective holes.
4. Carefully place the instrument panel applique into its assembly position.
NOTE: Ensure the spring clips are aligned with their proper holes. Press the applique into place. Ensure that all the spring clips are secure.
5. Install the eight screws retaining the upper finish panel. Insert the lower LH and the lower RH instrument panel snap-on finish panel inserts.
6. Connect the battery ground cable.
NOTE: On vehicles equipped with Electronic Engine Control (EEC), when the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the EEC processor relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.
