To replace the headlight switch, instrument panel dimmer switch, and trunk lid opener switch assembly, first disconnect the cable from the negative terminal of the battery. Remove the left end trim panel from the instrument panel, then reach through the opening in the end of the instrument panel to push on the back of the switch while prying it out with a trim removal tool. Disconnect the electrical connectors and remove the switch assembly, noting that if replacing the headlight switch, the entire assembly must be replaced. For installation, pop 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, again disconnect the cable from the negative terminal of the battery. Depending on the model year, remove either the center trim panel or the upper storage bin. Spread the release tabs to remove the hazard flasher switch from its location, or for newer models, use a plastic trim tool to pry the switch out between the two center vents and disconnect the electrical connector. Installation follows the reverse order of removal.
