Okay, newbie here. I have worked on my own and family vehicles since 12 years old, so not new to working on vehicles. The passenger door will not disengage to slide closed/open in the auto mode. When I shut off the auto mode, pull out on the handle it unlatched, then I place it half closed, turn on the auto mode, it will slide closed or open in auto. I suspect there is an actuator that disengages that latch before the slide actuator is engaged to slide open or closed. I also suspect it is bad because it disengages when in manual but not in auto mode. Does anyone know the part name and number and where it is located (about) before I dig into this? Or is this already been answered with video? Thank you.
