Have Toyota Questions? Ask a Mechanic for Answers ASAP
This question is going to be tough to answer because there is no information published on the fuse box removal for this car. I searched the major repair manuals and can't find anything other than the fuse layout. I would love to help, but it might be the kind of thing where you take pictures of your fuse box and I can then tell you where to start. If you are interested in help that way, please let me know. I have one 2005 sienna in my fleet, but it is a bait car and I rarely see it so I can't tell you from memory.
