The hazard warning switch is combined with a control panel that must be serviced as a unit, installed in reverse. In order to service the hazard warning switch on Lexus models, the cable is disconnected from the negative battery terminal, the center cluster finish panel is removed from the instrument panel and the radio unit is removed from the heater/air conditioning control panel assembly while separating it from the complete panel. To remove the power mirror control switch, remove the knee bolster trim panel, remove the driver's side trim panel from the instrument panel, release the electrical connector and the mounting clips from the back side, and reinstall it backwards. The one unit is the defogger control switch and A/c control switch that should be replaced as an assembly. To remove the instrument panel illumination rheostat driver's side trim panel should be removed and the switch carefully pried from the instrument panel, removed from the switch, and disconnected electrical connector. To install, reverse sequence. While the switch base has to be carefully pulled away from the center console, the power outlet electrical connector must be disconnected, the tabs released, then the outlet pushed through the panel to be installed-that is, the removal is the reverse of the installation. To remove the driver's side trim panel for the engine switch in smart key models, remove the two retaining clips at the back and pull the switch out of the control assembly, plug the engine switch wiring harness connectors together, remove the driver's side trim panel, installation is the reverse of removal.
