2005 Scion tC Parts Questions & Experts Answers

• Q: How to service and repair the A/C Switch in the heater control and accessory assembly on 2005 Scion tC?

  A: Service and repair work on the heater control and accessory assembly must begin with elimination of static electricity through contact with the vehicle body. Installation requires following the opposite sequence which removal did. Start with shift lever knob sub-assembly removal (manual transaxle) followed by console panel sub-assembly UPR FR extraction and then separate heater control and accessory assembly by unhooking its 9 claws while keeping the cover properly closed to avoid damage. Pulling the connector will enable whole assembly removal. Remove the center cluster module knob first, then take out the 6 screws from the heater control base lower to release the 2 claws until the air-conditioner panel sub-assembly comes off last. After that, users can remove the heater control lower by releasing the 4 claws. You should end by taking out the air-conditioner amplifier assembly after you free the first knob with one claw then free the second knob with an additional two claws and free the third knob with two more claws.
