Hi, apparently my 97 Villager has a short somewhere, which causes it to
lock itself with no warning. It mostly shows up when you push the
unlock button, about a half second later it will start locking the
doors. When it acts up, it will keep locking over and over, you
can hear it clicking. I've talked to other people who have
reported the same problem but no fixes, so I was wondering if this is a
known defect on these vans, and what the fix is. I can work on
testing each component, but would like a starting point if anyone has
one. Since it happens most when the passenger door unlock button is
pushed I'm thinking the problem is there, but it occurs regardless of
which unlock button is pushed. It will act up about every other
time with the driver side, but every time the passenger side is used it
goes nuts. This problem also means that the key has to be used to
unlock the door, and to unlock from the outside you have to put the key
in, turn, and leave until the door is open instead of just unlocking
the door, pulling the key out and then opening the door like you can on
any other vehicle. Thanks.

Well, I found the problem on my own. There is a TSB on this
problem. I was able to get a copy, requires a lot of work and a
bunch of parts. Problem is caused by moisture.

Where did you find the TSB?
