I just bought a 1999 740iL from a private party after my '97 740i was totalled.

The car I bought is great, but has a weird problem: I can't open the rear door on the driver's side. Something is apparently wrong with the cable or linkage that connects the outside handle to the latch. (You can feel that it isn't right.)

This would probably have been relatively easy to fix, but the seller, in messing around with the door, set the child lock so now it won't open from the outside cuz it's broken, nor the inside because of the child lock. it doesn't look like I can get the inside panel off with the door closed.

Anybody have any ideas? I was wondering if it might be possible to remove the outside bottom window trim and fish with a "slim jim" or some such. Again, any suggestions would be much appreciated.
