I have a 2002 Grand Caravan on which the passenger electric door lock
switch does not work to lock the doors, although it does work to unlock
them. Actually, I'm not sure it ever worked. What I want to know is
whether the passenger side switch is *supposed* to lock the doors--or
is it a safety feature to allow only the driver to lock the doors?
I have this same problem on a 2004 grand caravan. Mine does it on the
drivers side though. It will unlock the doors but not lock them.
Ocasionaly it will snap out of it and work fine for a day then go back to
unlock only. I think mine is a grounding problem. Sometimes raising and
lowering the power windows will trigger the locks. When the locks work
fine, the power eindows do not trigger the locks. These locks and windows
actually run off a negative trigger through different resistances to cut
down on wires. Lock and unlock are actually the same wire. That is why i
believe mine may be a grounding problem. Passenger side works fine.
It could just be a bad switch too.
Anybody have any advice on how to remove the interior door panel on a
Caravan? Any clips need replacing or tricks to getting it off without
