To remove the interior mirror, use a Torx bit to loosen the screw, slide the mirror up and off its mounting base, and disconnect the electrical connector if equipped. If the mounting base has come off the windshield, it can be reattached using a special mirror adhesive kit available at most auto parts stores; ensure to clean the glass and the mounting base thoroughly and follow the adhesive package instructions, allowing the base to bond overnight before reattaching the mirror. For installation, reverse the removal process. For the exterior mirror, detach the mirror cover by pulling it straight off, and if the vehicle has power mirrors, disconnect the mirror electrical connector. If the wiring harness cannot be pulled up far enough, the door panel will need to be removed for access. Next, remove the three nuts securing the mirror bezel and take it off the door. Installation is the reverse of removal.
