Window drops when I open the door, but then goes back up

Try disconnecting the battery, then putting the windows up/down. You will know if the "reset" worked if you have to hold the window button down to put the windows up/down the first time (one-touch shouldn't work the first time). If that is not it, it could be a faulty microswitch. I don't know if this will work, but you could also try raising and lower the windows by putting the key into the driver's door lock and holding it to the left and right (trust me it works). That may help determine if it the door lock is failing or if it is something else.

I've had & fixed that issue on a couple cars. Recently there was a discussion about buying the VW part (latch mechanism) to fix it much cheaper than the Boxster part. (Just be sure to get either the 8 or 9 pin electrical connector as needed.):

There is a part in the mechanism that rotates to latch and unlatch the door. That part pushes on a micro switch to let the Central Locking Unit 'know' when the door is unlatched.
On both of mine the rotating latch was made of metal with a plastic coating and the plastic had worn off in the part where the micro switch should contact it.

Well, holding the window down for 5 seconds, then raising again and holding up for 5 seconds did not solve the problem. Tonight after I get home I'll try the battery disconnect. Thanks for the suggestions.

I hate it when the car comes back from the shop with a brand new problem!
