97 toyota 4runner liftgate will not defrost,window will not open, wiper will not work

Have the same problem in a 2004 Toyota sequoia. No wires are pinched took to a dealership they are playing guessing games with what is wrong. Any one else have this problem?

If the wiper and defroster and window arent running I would guess that there isnt any power going to the rear liftgate. Check the fuses for each and replace if they have blown. Another idea: the wires leading to the liftgate may have become pinched or shorted. If you can inspect the wires from the car into the liftgate (it would be best to remove the liftgate case and examine liftgate internals)
