Avensis Electrical Issues??

Yep its very likely to be that button then buddy.

I think the idea is that you can disable the passenger airbag and have another child in the front passenger seat, something which would be a pain if you couldn't stop the operation of the window... Of course on a Celica you didn't get rear windows, just front ones. The amount of cars which were got for a knock-down price because the passenger window 'didn't work' was absurd!
