• Q: How to replace the A/C Switch in the heater control and accessory assembly on 2003 Toyota Corolla?

  A: The replacement process of the heater control & accessory assembly begins by removing both the console panel upper and the instrument cluster finish panel. To access the heater control & accessory assembly pull out the device by releasing the two fitting claws. Open the claw of the cable clamp with a screwdriver to disconnect the defroster damper control cable while safeguarding the cable wire from bending which could reduce assembly operational functionality; tape the screwdriver tip before usage. Open the claw of the cable clamp for a second time to disconnect the air mix damper control cable while keeping the cable wire straight. Detach the connector and unfasten the heater control with accessory assembly from its mounting position. To install the air mix damper control cable connect its inner end to the heater control lever and place the outer cable into the cable clamp without bending the wire part. Use the heater control knob to check the operation at both ends of MAX to ensure proper stopping occurs. COOL and MAX. There should be no recoil when operating the MAX. HOT position on the heater control knob and the outer cable should never come apart when tugged. Duplicate this cable installation for the defroster damper control by linking the inner end to the heater control lever followed by cable clamp attachment to the outer end while remaining sensitive to cable wire conditions. Inspect the heater control knob function by moving it between FACE and DEF positions without recoil then ensure the outer cable stays secured. Settle the ends of the connector and mount the heater control & accessory assembly.
