Driver side power door opened ok when w first got the van but shortly, it began closing almost all the way then reversing, only to almost close and reversing. this would happen a few times. You could push it closed if you were standing there. A mechanic tried lubricating the moving parts and it seemed to work better. The passenger door would only open if you jerked the handle several times both sides would close pretty consistently when you hit the door jamb switch. The owner's manual gave instructions for trouble shooting the system. it referred to fuse 5, 27, and 29. ait only gave instructions regarding fuse 29. We followed the instructions and now both doors are not power doors anymore. Does anyone have experience with this problem?
