How to replace the A/C Switch in the control assembly on Scion tC?

The first step to handle the control assembly replacement is disconnecting the cable from the negative terminal of the battery followed by a minimum 90-second waiting period to stop Air Bag and seat belt pretensioners from activating. The first step involves uninstalling the shift lever knob sub-assembly that serves the manual transaxle while also removing the console panel upper front and instrument cluster finish panel assembly by unplugging 9 claws and keeping the heater control cover properly closed. Remove the heater control while disconnecting its connector. Follow these steps for instrument cluster finish panel assembly installation: firstconnect the connector then reattach the 9 claws and put back the instrument cluster finish panel assembly before setting the console panel upper front and the shift lever knob sub-assembly for the manual transaxle. Upon reconnection of the cable to the negative battery terminal follow initialization procedures since specific systems need this step when disconnecting and reconnecting the cable.
