A quick basic answer: A] unhook Negative battery terminal B]remove
the door latch; any other door panel screws, GENTLY pry the door
panel (Assuming the arrest is built in and not attached separately) out
from the frame -keep checking for any missed screws- with a plastic
putty knife or a panel puller, watch for plastic clips/pins that hold the
panel and keep any that are not broken -inexpensive replacements
available at Toyota dealer ---, C] on the inside of the armrest/panel
locate the switch wires-unplug- and remove the switch and replace
with the new one. D] reassemble in reverse order.
E] reconnect the Negative battery terminal. F] ;-) run the window up
and down a few dozen times just because you can..;o)
Good Luck Hope this helps
