Outside mirrors for Toyota models require prying off the mirror trim cover on the inside of the door, disconnecting the electrical connector from the mirror (if equipped), and removing the three mirror mounting nuts. The mirror can then be detached from the vehicle. For installation, simply reverse the removal process. For Lexus models, the door trim panel and window frame trim need to be removed. Then, remove the three mirror retaining nuts and disconnect the electrical connector. The mirror can be carefully pulled up to disengage the retaining clip and removed. Again, installation is the reverse of removal. For inside mirrors, disengage the sensor cover clips, then remove the cover(s) and electrical connector. To remove or install the mirror, remove or install the Torx screw at the base on the windshield. If the mount plate itself has come off the windshield, adhesive kits are available at auto parts stores to re-secure it. Follow the instructions included with the kit.
