I just had to reply....it's back. What a weird one.

So far have gotten and error message twice "after the fix", here are the consistent things
  • Always the driver side sliding door, like last time
  • In the AM before the first start, van is garaged so it's not getting super cold
  • A manual open/close resets the door, then goes back to normal operation, even with engine off (wondering if there was a battery voltage issue)
  • Passenger power door works completely fine
I guess back to the dealer, need to wait for the error to come back so might be awhile. If I get lucky and the message happens at home, I'll try to check the battery voltage, still don't want to write that off just yet.

FCA was the original owner before I bought the van used, surprised they didn't run into this, if this keeps up might need to swing by the tech center, smart money is that there is a DRE out their that knows what's really going on. Save that for the 4th visit ;)

So my leading guesses (pure shot in the dark, FCA has locked down their CAN bus and the van is under warranty, so they can do the diagnosis):
  1. FCA has a bad habit of putting harness connectors in silly places, so let's go with my fav: moisture intrusion into connectors, creating sporadic electrical issues
  2. Software: module wakeup not happening correctly from sleep

It does make sense to check the batteries.

Once again time will tell if the fix is permanent. They applied a software update: "1819319B PSD Module Update"
I just had a bulletin related to the sliding doors applied to both door modules last Friday. Will let you know if the issue comes back.

Cool, farther back in this thread it looks like there were software updates that did not fix this issue. Hoping it's a new update. Either way, I still have a far amount of warranty left.

There is no red switch, people were playing around with the wiring harness connector that happens to have a red locking tab. Knock yourself out playing around with the connector, but I doubt that's the root cause for the door issue. FYI since the software update the power door seems to be working 100% of the time. Now, beforehand they replaced the door module and latch assembly. So who knows if it was a software issue the entire time, or if it was a combination of issues that needed to be addressed. My post talking about battery voltage and wiring was a red herring.

mjr0483,

I had this exact problem today and figured it out. The online manual states if there is something obstructing it, it shuts off. To reset it, here's what I did. There is a small black box under the track where wires run into both sides. On top you will find a red switch. Switch it in the other direction, leave for a few seconds, then switch it back. Then pull the door all the way back until it clicks and locks. Make sure it doesn't slide forward at all. Then pull the handle out and slide the door to the closed position. When closing, you should feel some resistance. When fully closed, try the button then. Hopefully this will fix it. If not, could be another deeper issue. Hope this helps!
The red switch on the block you are referring to is a lock for the electric connection, does nothing to reset anything SMH...

Had the same issue with the driver ride sliding door and I did some of the recommendations here. I did a soft reset by disconnecting the battery fo 10 mins, checking the fuses, checking the connection under the track. I was resigned I would have to take it to the dealer. I tried one more thing. I opened and closed first the passenger side door and then the tailgate using the fob keys. I pressed the driver side button on the fob and voila it worked!

Lucky you. I had the same thing. I believe is the interior handle that get stock. Happens more frequently because is more used

Welcome to the forum.
If you put your van info in the signature line of account settings it will show up at the bottom of your posts and will help us answer your questions easier. The build date is on the edge of the driver's door.

What is the problem with your door? Sometimes the handle needs replaced (hardware), other times something can be flashed (software). The sliding door reversing instead of latching was a software issue for my van.

The message "power door unavailable" could also be related to not having the shifter in Park. No rolling drop offs with this van.

Umm, the red switch you are referring to is the lock keeping the wire harness together, it is not a reset switch:rolleyes:

I know this post is 4 years old, but I had the same problem today. I opened the door all the way, moved the switch to the other direction, then put it back after 5 seconds. I pushed the door back into the fully open position (it was almost there to reach the switch) and didn't need to do anything else. Once the door was in the fully open position it closed by itself. Did an open and close with the handle button to make sure it was working that way and everything is fine. Thanks!

So far so good on your FW update? I gave up after taking my car to dealership only to have it sit at the lot for weeks and see no improvements whatsoever or to get ridiculous comments about my dash cam causing interference with the door..

@tyc Doors work great. They really had to load up the parts cannon:
Visit 1: new door module installed, new module reported error with latch, latch replaced
(door errored out after a week or two)
Visit 2: Firmware update.

Now was it just the firmware or is it firmware + some combo of parts above, I don't know. But I have had 0 issues with door since my last visit. fyi sliding passenger side door lock failed later on, that was just a latch replacement.

Since the door seems to self heal, when it errors DO NOT TOUCH it. Bring it to the dealer as-is. Yes that means not touching the door for a few days, but I think it helped get the tech off on the right foot. I went as far as taping a note to the door that said "do not open, read door module codes first".

And the connector with the tab on it that people keep playing with, it's not the root cause, the issue will come back.

Is it related to the fuel door? I know that the power sliding feature turns off if the fuel door is open as a safety feature to prevent opening while gassing up. Maybe the fuel door wasn't closed all the way?
Same thing just happened to me today. 2017 Pacifica Limited Driver side sliding door, error message on dash “power unavailable etc...”. Thank you for the suggestion to check the fuel door. I cycled the fuel door and now the sliding door works perfectly. This forum is a gem.

This just happened tonight, but only on the drivers side sliding door. The passenger is fine.
Any method to open or close the door is met with chimes and a error in the dash, Power unavailable, operate manually.

is this a failure or did I turn this option off somehow?
Open your drivers sliding door & look I for a black box with

Open up your sliding glass door all the way until it locks open and look in the track there’s a little black box that has wires attached to it on top of that black box is a red switch you need to pull it move that switch all the way to the left which turns it off and then push it all the way to the right as far as it’ll go and then leave it alone and your door will open and close like it’s supposed to
