Strange problems Please help

hello!

I own a 1992 300SL, I got the car second hand and i noticed a couple of problems. I hope you guys could help me out..

1) The driver and passenger side door locks automatically open after hard braking or if the rollbar automatically engages... it seems that the locks are either haunted or are too sensitive??
Also, the door locks do not automatically close when the car is being driven.

2) the central vacum locking system is not working.. the previous owner cut the vacum line in the center glove compartment and stuffed it with a screw...argh.. I can hear the vacum pump whirring whenever i lock or unlock the car or use the lock beside the spectable compartment... but still all the compartments (door armrests, etc) that require vacum locking, dont engage when i try to lock them.

3) When the softop is on, there are anodized flaps that are opened behind the driver and passenger seat. The problem is that the rollbar rubs on the passenger side flap and its annoying and damages the leather... any fix?

Please give me some advice on how to solve these problems.

also, is there any workshop manual or parts cd out for this type of SL?

thanks so much!
