I've got a big problem:

I never lock the car- but can.

When I pull the drivers handle from the outside, it locks.
I used to be able to open it- by pulling up on the lock pin by going through the rear passenger door- until today.

Today the rear passenger door pin screwed up- it pulls up/down without any engagement- it's permanently locked and will not open from the inside or outside.

I can open the drivers door with the key.

Any suggestions on getting into the doors to fix and unlocking the back and disabling the auto locks all together??

THANKS!!!!

 

First thing I would do is check if there is a fuse for the door locks. If there is one, perhaps it burned out. Second is to find a wiring diagram for the door lock system. Then work from there.

 

There is control box for the locks inside the driver's door, just below the handle, it is connected to the trigger of the handle. Take off the door panel and see the problem is--probably the rod needs adjustment. I had the same problem with my 1992 940GL... fixed it.
