Hi, I have a 1998 Chevy venture. The problem I am having is... the power sliding door will close by itself, but will not open by itself. I have checked the fuse,and it seems fine. When I use the overhead button to close the door I can hear clicking, but it will not open. Could there be a problem with cable or something?? I have cleaned the sensors on the inside of the door. still the same problem. any help would be appreciated. thanks.
