For 2007 and earlier models, the dimmer switch is mounted in the overhead console. Begin by disconnecting the cable from the negative terminal of the battery. Next, remove the left end trim panel from the instrument panel along with the left side trim strips. Using a trim tool, pry out the driver's side switch panel and disconnect the electrical connectors for the dimmer switch and the driver information center switch from the backside of the trim panel. To remove the dimmer switch, pry the switch panel out of the trim panel with a small screwdriver, then remove the mounting fasteners and the driver information center switch. Disconnect the electrical connector and take out the dimmer switch from the trim panel, then install a new instrument panel dimmer switch into the bezel, ensuring it snaps into place, with installation being the reverse of removal. For the hazard flasher switch on 2007 and earlier models, pry out the center air vent and disconnect the hazard switch electrical connector, then release the tabs securing the switch to the vent panel, with installation being the reverse of removal. For 2008 and later models, the hazard flasher is part of the radio control assembly and must be replaced as an assembly; start by removing the center trim radio and heater/air control panel, then take out the radio control assembly from the trim panel and have the unit tested, with installation being the reverse of removal.
