I have a 2006 Sienna LE and today my back/trunk rear door wouldn't open. I pull on the black latch in the back and there is a clicking sound, but it won't open. When I click the lock/unlock button on the FOB or in the car, there is no locking/unlocking sound from the back door. I have removed the plastic cover from inside and tried connecting and reconnecting the wires associated with the locking mechanism, but nothing worked. I have also tried to manually to open the door from inside, but when I flip the latch inside (gold pin) nothing happens. Any suggestions would be really appreciated!
