Thanks for the info guys, turns out that the rear wiper wasnt completely seated and was ajar after all.


#1 most common problem I list on the rear window page:

So what are the most common problems that are encountered with the rear window?
#1 is the rear wiper not fully retracting and closing its switch. If the window relay doesn't think the wiper is off the glass, it won't move the window, up or down. In
the 1st gen 4Runner you can also have neglected to reconnect the window wiper connector inside the rear driver's side corner.
