• Q: How to replace the A/C Switch in the Heater or Boost Ventilator Control Assembly on 2005 Scion xA?

  A: The procedure for replacing either the Heater or Boost Ventilator Control Assembly begins by removing Instrument Cluster Finish Panel Garnish No.2 and No.1 and proceeding to remove the 3 heater control knobs. The replacement of Instrument Cluster Finish Panel Sub Assembly CTR will require removing four screws while dislodging four clips along with a claw and disconnecting the connectors. The installer must detach the Heater Control & Accessory Assembly by disengaging three claws while disconnecting it. They should use a screwdriver to free the defroster damper control cable sub assembly and the air mix damper control cable sub assembly from the cable clamp while ensuring the wires remain unbent to avoid operational interference. Use screws to tape the tip of the screwdriver before operating it to prevent damage. First disconnect the air inlet damper control lever by unclipping the claw followed by disassembling the heater switch assembly through 2 screws removal. The next step requires you to eliminate the Heater or Boost Ventilator Control Assembly. When installing the component you must connect the inner cable end of the air mix damper control cable sub assembly to the heater control & accessory assembly before fastening the outer cable on the cable clamp. Keep the cable wires straight to prevent operational failures. Verify that the heater control knob receives complete resistance throughout its MAX. COOL and MAX. HOT positions. COOL and MAX. Test that the heater control knob stops at both MAX. HOT and MAX. COOL positions without cable recoil alongside an assessment of the outer cable not disconnecting when pulled. The inner cable end of the defroster damper control cable sub assembly should be attached to the heater control lever before securing the outer cable on the cable clamp. Connect the connector before installing the heater control & accessory assembly by verifying the cable wire maintains its straight alignment and checking for correct heater control knob position at FACE and DEF ends without recoil effect and that outer cable engagement when pulled.
