1988 420SEL

Hello, I have 1988 420SEL with 170K miles. The vacuum lock will unlock and lock all doors. However, the rear driver side door will unlock but will not lock. I have to manually lock it.

I have searched the forum but unable to find the answer.

The car vacuum actuator was replaced last year at the MB dealer. I hope not to spend another >$1K-$2K again at MB dealer for the lock issue.

Suggestions welcome. Thanks.
