i have no issues now. i have the TH so no sunroof. i did have to go back in and check all of the connectors to get the window working. i'm guessing it's a simple connector issue. i do like to have the battery disconnected when i do anything electrical. not because its dangerous (it's not) but because of all of the flaky sensors and software in modern cars that has not been tested for any edge case. but the issue i had was exactly with the back window.
Did you only disconnect the main engine battery, the 12V in the back (hybrid), both? Working on the connectors this weekend to fix the back hatch switch….

only the main normal car 12v battery - it's in the back in the TH. not necessary to mess with the hybrid battery, i wouldn't know where to start but also not necessary.

my message to "the people" is to beware of breaking the fragile and rigid piece of trim around the light console. it's easy to break and while probably costs 2 cents, it's not replaceable/obtainable. only because i am freakishly handy i was able to restore mine to not-noticeably-being-broken.

goto any good repair shop and they can order that replacement part for you if you cant thru the toyota parts department.

some of the big toyota online parts stores will have a full breakout of the parts you can order but finding it can be a pita to find it.
