Power door lock inoperable on passenger sliding door only

You need to remove the inside panel of this door, and confirm the inside lock button is broken...you can first try this at your local salvage yard...then do it on your Van...be sure to keep the assembly from the salvage yard...as you may need some of the pieces...the dealers still sell the complete assembly but cost is much higher...Hope this helps.

Check the fuse, wires and the motor, could be some bad connection too

Check the fuses in the fuse box.

check the tracks that it rides in and if clear it may need some lube!

I just had mine fixed at the dealer for the same problem. Their first response to me was "this happens ALL THE TIME". He said there is a little plastic pin in the door handle assembly and the pin has been known to slip out of the assembly. However, when they got inside, they said it was the actual door handle (inside) that was broken and had to replace the whole piece. So, the first step according to my dealer/servicer would be to check for the little plastic pin.

2006 chrysler town and country passenger side window suddenly stopped working.
other windows work, sliding doors work as does rear hatchback.
fuses seem to be good.
might there be a safety switch that somehow got pushed that keeps the passenger window from opening?
