'04 Jetta GLS. Drivers rear door does not open (unlatch) from inside the car. The child safety lock switch is in the open position. Swich seems like it works fine. Today I pulled the door panel thinking that the cable may have come free from the door handle. No dice, the cable is connected and when I pull the handle it makes a sound back at the latch (a normal sound, like the latch is going to release) but it does not open. Any ideas what is wrong?
