I have tried all of the threads on this issue, starting with the most common,
and nothing has worked, Where is the controller located ?  relay board that
operate rear window defog, and up/down is located drivers side behind the
front seat behind the plastic trim. - Is this located in the aft cargo area on the
left side of the auto? How do you get to it when you can not lower the aft
hatch(window up and not working)?
