power locks are cattywampuss on 1997 Mercedes-Benz S320

My power locking system is acting weird. The door locks don't go down in unision and the trunk will pop open by itself while I am driving. Is this a vacuum assist pump gone bad...appreciate any ideas. CK

The locks going down as you mention can be caused by a leak in the system causing unequal vaccum to the different doors. The trunk opening while driving is unrelated and will need diagnosis. Good luck, Greg
