I'm having trouble with the power sliding door on our '01 Grand Caravan. It always closes ok, but won't always open. Hitting the "open" button, either on the console, the doorjamb, or the remote results in the door kicking out as if it's going to open, and I can hear the motor kick in, but then the motor stops without moving the door. It seems to do this more frequently when it's cold out (Chicago winter), or when the van has been sitting overnight.
Google turned up this newsgroup, but I haven't yet found a previous message mentioning a problem like this. Suggestions appreciated.
