I have a 2004 Sienna that started having a problem with the right side power door recently. When I pull the door handle from the outside, the door opens and shuts as expected however, when I use any of the remote buttons it acts as if the latches that hold the door shut/open don't release so the door won't automatically open or shut as it should, although it tries and fails. Is the the ECU causing the problem or could it be something else? If it is the ECU, does anybody know what the part number is so I can make sure I order the correct part.
I have had the battery checked.... good. I have performed the reset a couple of times to see if that is it.... no luck. We currently have it turned off until I figure out what the problem is. I understand it is a pricey fix for the dealer to perform and I can do it myself if I can get the right part.
Thanks for any help.
