The passenger front window won't go up all the way in auto mode. It will go up all the way in the normal mode. In auto mode, it acts like a trap sensor stops it at half way and lowers it about an inch. I've lubed the regulator, disconnected the door control module, R & R'd the window motor, without any luck.

Does this regulator have a trap sensor? And, is it mechanical (i.e part of the regulator), or does it sense a spike in motor current?
