Those of you who guessed that the linkage was the issue, give yourself a gold star. Took the door panel off today and found that the linkage had slipped out of the plastic clip that the lock works. It looks like a piece of it broke off. It looks to me like it will easily happen again unless I change the part. It is part #003 988 50 78. Hard to tell from the EPC how big that slit in the side of it is supposed to be. Anyone know?
