Fuse 17 of the inside fuse box appears to be a 20 amp that powers the
cigarette lighter and DLC (diagnostic connector).  Do you use any
accessory adapters in the cig lighter?  Any signs that it could be
blowing the fuse... a burned appearance on the contact terminal inside,
anything?

Fuse 3 in the fuse box near the battery is the main power source for
the rear window (the back glass window).  It would blow if there was a
motor or motor wiring short.  Perhaps you simply have a bad switch.
Have you tried taking off the trim, then manually apply ground to the
violet/green or violet/blue wires at the motor harness?  If you are in
there, check for ground at the black and black/white wires, as well as
B+ at the yellow/green wire (always) and at the black/pink wire (key in
run or accessory position).

Finally, I don't know if there is a window cut switch for the back
window, but if so I would check to see if it has been inadvertently
pressed.
