In order to replace the Inside Air Temperature Sensor ("Overhead"), the left windshield garnish molding must be removed, followed by the left center pillar assist handle, left center pillar garnish molding, and left sunshade. Then, remove the retaining screws off from the headliner and pull it downward to inspect the sensor. Remove and disconnect the headliner's inside air temperature sensor electrical connector. For installation, hook the new inside air temperature sensor into the headliner and attach the electrical connector back in. Fasten the headliner with screws and install the left sunshade, the left center pillar garnish molding, the left center assist handle, and, finally, the left windshield garnish molding.
