  Q: How to troubleshoot and repair the A/C Switch on Scion xA?

  A: The first step for repairing the HVAC control assembly requires users to disconnect the negative battery cable and wait 90 seconds to stop Air Bag and seat belt pretensioner activation. Remove first the heater control knobs before dismantling the number 2 and number 1 instrument cluster finish panel garnishes. Service the instrument cluster finish panel sub-assembly center by first unscrewing 4 screws and then detaching 4 clips and a claw before disconnecting the connectors. Start by unclipping the cables that connect the defroster damper control to the heater control and accessory assembly through three screws and the screwdriver-detached cable clamp claw. Stop the cable wire bending. Detach the claw from the air inlet damper control lever before removing the heater switch assembly by unscrewing its 2 screws. The heater switch assembly should be installed first and followed by the air inlet damper control lever for installation. Connect the inner and outer cables of the air mix damper control cable while the defroster damper control cable must function properly with straight wires in place. Begin by connecting the heater control and accessory assembly through 3 screws and finally put in the instrument cluster finish panel sub-assembly center by matching connectors while attaching clips and claw and screwing in 4 pieces. The procedure ends with the installation of heater control knobs followed by attachment of the No. 1 and No. 2 instrument cluster finish panel garnishes and battery cable connection to the negative terminal before system initialization for post-battery-reconnect requirements.
