Help! My Power Windows Won't Close All The Way!

Hi everyone I own a 99 Boxster. I've experienced a problem with my power windows and will appreciate any comments or thoughts.

After my car has been sitting outside my driveway for 2 months i've decided to take it out for a ride. After i started the car and closed the door, both driver/passenger windows suddenly automatically rolled down 1/4 of the way from the closed position (i thought this only happens when i unlatch the convertible top). I am aware that the windows should open about half an inch to clear the rubber seals when opening the doors but this isn't the problem I have. This has never happened before. I tried to play with the power window switches to see if it would close back up all the way but I got no luck. I even tried pressing the switch for the convertible top and tried different combinations of pressing the power window buttons and convertible switch button. I also tried stepping out of the car, locking it, and getting back in to close it but nothing seemed to work. After doing this for around 5 minutes, both my windows were able to roll back up. Everything seemed to resume back normal after a couple more tests of rolling the windows up and down (the windows work perfectly including the automatic movements/touch function).

To make a long story short, I got onto the freeway with my windows shut tight. After I hit a small bump, both my windows AGAIN automatically rolled down 1/4 of the way from the close position. Please keep in mind that the mechanics of the power windows both work fine; they can open the whole way but will only close 3/4 of the way. Seems as though it has some kind of a memory issue in thinking that the windows are fully closed when there is still 1/4 of a way left. If someone experienced this same problem before or knows anything about it please advise. Thank you so much for your time.

Hi

There are two main reasons for this problem - the convertible switch and corrosion in the connectors in the A pillars.

If both windows rolling down at the same time, there is a great change that the switch gives the problem.
