Today I took the door panel off of the front passenger door to try to
diagnose what's up with the locking mechanism.
Symptom: door does not lock when driver door lock is engaged, however
door does unlock when driver door is unlocked and vacuum is charged.
Watching the mechanism, the actuator from the vacuum valve is sliding
down in a slot that would activate the lock, were the slot not there...
It appears, by looking at the service manual, that there's supposed to
be a little spring that makes the locking mechanism activate, but I do
not appear to have this part. Does anyone have any suggestions for this
piece? I can't figure out how to search for this type of thing at
Autohaus nor at Performance.
