Lexus 84970-0E120 Switch Assembly, COMBINA

Disconnect the negative cable from the battery. For Highlander models from 2013 and earlier and Lexus models from 2009 and earlier, remove the center trim panel around the A/C Switch, or the trim panels around the shift lever leading to the A/C Switch for Lexus models. Once the trim is removed, the mounting fasteners will be exposed; 2003 and earlier Lexus models have two fasteners at the bottom of the A/C Switch and audio unit, while 2004 and later models have four. After removing the fasteners, detach the audio unit from the A/C Switch by removing the mounting bracket screws. Pull the assembly out slightly and disconnect all electrical connectors. For Highlander models, remove the mounting screws for the A/C Switch and audio unit. Installation is the reverse of removal. For 2004 and later Highlander models, the A/C Switch is mounted to the center trim panel. Pry the panel outwards to disengage the clips and disconnect the wiring to the A/C Switch. Remove the two mounting screws to separate the A/C Switch from the center trim panel, with installation being the reverse of removal. For 2010 and later Lexus models, the radio unit must be removed, as the A/C Switch is incorporated into the radio receiver and navigation unit. Installation is the reverse of removal, followed by running the engine to check for proper functioning of the A/C. For Highlander models, pry the rear A/C Switch out of the center console, disconnect the electrical connectors, and remove the A/C Switch, with installation being the reverse of removal. For 2018 and later Lexus RX350 models, use a trim tool to pry the rear A/C Switch out, slide it towards the front while pulling the panel outwards, disconnect the electrical connectors, and then install the A/C Switch by connecting the electrical connectors and snapping the panel into place. Finally, run the engine to check for proper functioning of the A/C.
