The power lock switches on the front doors doesn't unlock the locks. The switches will lock the locks and the Key will lock and unlock all locks. Ive taken the switch and door pannel off and checked the wirring. There are three wires going to the switch one light blue with power one black (I'm assuming thats the ground) When I jump the blue and black wires the doors lock. There is also a white wire but when I jump it nothing happens. I'm assuming that this wire should have power and when the cirrcut is closed the doors would lock. Is this assumtion correct and if so where should the power be comming from.
I've isolated this white wire and tapped into the unlock wire from the key lock and wired it into the switch. with the switch jerry rigged like this the doors unlock but you have to hold the switch down for a while and the dome light comes on if ignition is not on (just like when you use the key to open all door locks)
I'd like to get this fixed correctly.

Look under the passenger door sill and look at the wire loom. There is a splice in the loom for the door locks alot of times it will be wet and corroded.
That is what it was. The splice was so badly coroded that the wires wern't even touching. The tape was all but disintegrated and what ever had been holding the wires together was a tinny green powdery glob. I reconnected the three wires with a twist connector and sealed them. The windows work like they are suposed to now.
Thank you verry much for the help I doubt that I would have ever found that splice with out it.
omg. I had the same problem and found the wiring under passenger door sill horrible (2004 Venture). Big pile of muck and everything was really wet. I took all the tape off the wiring and spread the wires out and found a couple of splices in terrible shape and one was completed corroded and apart. I spliced averything back together and the door lock switches work again. Thanks. I must say though the wiring is way sub-standard. They used different colored wire to splice the wires. For example, they used a short piece of purple wire to splice together white wires. This in my opinion is below code.
