• Q: How to Service and Repair the A/C Switch in the Heater Control Assembly on 2000 Toyota Tundra?

  A: The first step for servicing or repairing the heater control assembly requires removal of the center cluster integration panel followed by taking out 3 heater control knobs and 5 screws then gently pulling the integration control panel from specific areas before disconnecting its connector. Afterward remove the lower LH finish panel as well as the heater to register duct No.2 and glove compartment door and the lower No.2 finish panel and heater to register duct No.4. Following the disconnection of cables you should break away the heater control assembly after removing its connectors. The installation requires you to connect all connectors before placing the heater control assembly in its proper position according to illustrations. The old assembly should be installed according to its previous placement or replace with a new unit using identical methods. Follow these steps to adjust the heater control cables when the mode control dial is set to "FACE" and the temperature control dial is "MAX. COOL". Adjust the mode control cable by pulling the air inlet control link to "FACE" and connecting the control cable as well as locking the clamp followed by light tension on the outer cable in the proper direction. The procedure should be repeated for the air mix control cable and water valve control cable where both elements need to be "COOL." The installation sequence following adjustments calls for heater installation at register duct No.4 then the finish panel installation at No.2 and glove compartment panel followed by heater installation at register duct No.2 along with the lower LH finish panel. The last step is to install the center cluster integration panel by removing the cover during heater control assembly replacement before connecting both connectors with 5 screws then restoring the heater control knobs.
