I tried unsuccessfully to lock/unlock all the doors from the passenger side on my '84 300D, but just thought something was defective. Are you saying that's normal?
That's normal. And if you've ever been inside the doors of one of these cars (versus the later ones), _why_ will be instantly obvious. You are, however, supposed to be able to unlock the passenger side all by itself, unless the lock spring toggle mechanism is broken (as it was in the Chicken Wagon for a period of time). The advantages of the later system are legion. The only downside is when the pump fails. (Rare, unless we're talking about the evil early 126 system.) -- Jim
