Doors not working

The first thing I would do is have the van scan for codes not with a diyer scan tool ether it won't read all the codes door codes etc. It will take a professional scan tool that can read all the codes. There are for codes etc that will give us a starting point.

I posted the description of operation and the trouble tree for the door inop under power. As you can see from the trouble tree the first step is check the door for binding then check for trouble codes.J4 in the fuse diagram is for the drivers door node.

There are a ton of codes for the doors as well as a lot of different reasons for them being inop. That is why getting the codes are so important also most likely you will need a scan tool that can read door data to help diagnose the problem.

The sliding door trim panel can be removed and a pin may have been dislodged. It seems impossible but it is held in mostly by clips that pry out with the panel. With door closed. A handle cover and couple of screws also. It comes off, take off plastic, and use a flashlight to check for a missing long pin, that may have come unhooked from the latch system. Common problem. Ok
There is room, just tight.

Depends where the auto alarm comes into the circuit I would expect. Whatever is before the alarm system is probably where the problem lies-relay, switch?

First check if the power lock works properly. If it doesn't, the lock motor is broken on the end and is locked up. That will prevent the mechanism from unlatching. Look at the linkages too. They are like a threaded wood screw on the end and they just snap into spring-metal clips, then "magic" holds them in. Sometimes that magic wears off and one pops out. Usually it's the one for the rear latch that comes apart. Chrysler has designed a lot of nice stuff over the years. That latch plate is not one of them.

I was wondering myself what is the best thing to use for that. I have tried silicone spray but it stuck next wet day/freeze night within a week. Oil might be the ticket maybe baby oil?

Silicone Spray Lube. You'll find it at the Chrysler dealer's parts department, any auto parts store, or any hardware store. It sprays on liberally like water, evaporates, then leaves a film of "slippery" behind. We use it all the time for sluggish power windows where bug juice, tar, and road dirt get into the rubber channels. I use it once a year on the seat belt webbing on my '88 Grand Caravan when it doesn't want to retract smoothly. It also works REAL well when trying to slide a tight rubber hose onto a metal pipe.
