Difficulty: Beginner · About 25 min · Toyota Sienna

Replace the master power-window switch on a 2004–2010 Toyota Sienna by removing the door-pull trim and transferring the switch wiring.

Steps

1. Open the door-pull panel

   Switch off the ignition and open the door-pull compartment. Remove its retaining screw and carefully lift the pull trim from the door without bending the clips.

2. Remove the old switch

   Unplug the switch harness and remove the remaining switch fasteners. Lift the switch assembly from the pull trim and compare its connector and shape with the replacement.

3. Install the replacement switch

   Seat the new switch in the trim and start its fasteners by hand. Secure the switch, reconnect the wiring plug, and confirm the connector lock engages.

4. Reassemble and test

   Press the pull trim back into its opening and reinstall the screw. Turn on the ignition and test each window from the master switch before closing the door.

Check your vehicle’s repair manual for exact specifications and fit.
