They can be found on the scionlife forums, or at least used to be. I bet if you ask around you’ll find them.

(Aside, it’s interesting that car people seem to be one of the groups that still use old fashioned BBS-style web forums.)

If your public library offers access to a repair manual database (many do), you can probably find it on there for free.

I just checked and both Auto Repair Source and Chilton have manuals for that car in their database.
