How to replace the passenger side power window switch on a 2003 Toyota Sienna?
I believe the design of the 2003 Sienna interior is identical to
that of the 2000 Sienna which I own. The switch module on the
driver and passenger sides are affixed into the armrest in the same
way. They have a plastic retaining tab on the underside aft end and
a spring-loaded metal clip on the underside forward end. During
installation, they are made to slide in rearward at the aft end and
then drop/snap into the mounting opening downward from the front.
Therefore, the removal process is the reverse; that is, release the
metallic snap latch at the front end and lift the front of the
switch module ... after the bottom of the switch module has cleared
the top of the armrest, you can slide the module forward to release
the plastic latch at the aft end and take the switch module out as
a unit. Disconnecting the wire connector frees the module for
further work. The problem is that the release point on the
spring-loaded metallic clip at the forward end of the switch module
is about 1/4" below the underside surface of the module; therefore,
simply using a small flat screwdriver inserted under the lip of the
module won't work, because it cannot engage the release mechanism,
which is a bit below. What really works best is a paint-can opener
(available from any Home Depot), since it has a bent end. Using a
flat screwdriver to slightly lift the forward end of the switch
module, and with the bent end of the paint can opener pointing
downward, insert it under the lip of the module at its center.
Pushing this makeshift tool rearward will allow the bent end of the
paint can opener to release the metal retaining clip at the forward
end of the switch module. You can then lift the forward end of the
module as descried earlier. Hope this helps.
