Ok, shut-up already!
1. Ok, I want ro revise my earlier post. I assumed that the passanger side came up normally.
2. Sounds to me that you are not getting enough vacuum to the actuators. You need a vacuum gauge and a vacuum pump. You can get the pump at Autozone for under $30.
3. Check the integrity of the coffee can and all the lines to and from the switch. The switch should also be checked to make sure that it is allowing the full amount of vacuum to the correct circuit as it opens and/or lowers the doors.
4. However, before I ran myself ragged checking each inch of line, I would make sure there is enough vacuum coming from the intake first. Then check the amount of vacuum at each major component including the switch all the way to the actuators.
5. A leak anywhere in the system can cause insufficient vacuum to lift the door shut.
