The power door won’t open completely when pressing the inside button close to door. When pressing the button to close, the door will try to close until it is almost completely closed, then it will open as if it detected something blocking the door. Any suggestions? A bad roller? Something on the track? I turned off the power door option and open/close the door manually. I don’t have a remote. Thanks

I started having issues with the power doors maybe 10 yrs ago, when the van had maybe 100k on it. The first time I went to the dealer and they just greased the tracks and it was working fine for a while. Later the problems persisted and I tried to re-initialize the door controllers. I found TSB BO024-06 that explains the procedure (no tools required, just a sequence of button pushing). I think the owners manual also has a similar procedure that was slightly different but worth trying. That helped for a while, then at about 160k I finally got fed up with it and just removed the 2 cables from each door so they would revert to manual operation. I think there are one or 2 computers that control the doors and when they go bad the only real solution is to replace them. I wasn't about to spend the $ to do that since we rarely use the back seats anyway. Our van now has 200k and still running strong. Here is the TSB procedure in case you want to try it.

1. Push the “MAIN” power switch to the “OFF” position.
The “MAIN” power switch is located on the instrument panel, left of the
steering column.
2. Confirm doors are closed, lights are OFF, and the key is out of the ignition.
3. Disconnect the negative (--) battery terminal and wait 60 seconds.
4. Reconnect the negative (--) battery terminal.
5. Push the “MAIN” power switch to the “ON” position and wait 3 seconds.
6. Push the “DOOR R” switch to open the right door and wait 3 seconds after the door
is completely opened.
7. Push the “DOOR R” switch to close the right door and wait 3 seconds after the door
is completely closed.
8. Push the “DOOR R” switch to open the right door and wait 3 seconds after the door
is completely opened.
9. Push the “DOOR R” switch to close the right door and wait 3 seconds after the door
is completely closed.
10. Push the “DOOR L” switch to open the left door and wait 3 seconds after the door is
completely opened.
11. Push the “DOOR L” switch to close the left door and wait 3 seconds after the door is
completely closed.
12. Push the “DOOR L” switch to open the left door and wait 3 seconds after the door is
completely opened.
13. Push the “DOOR L” switch to close the left door and wait for the door to
completely close.
With ignition in the “ON” position and both power sliding doors in the fully closed
position, the “PWR DOOR” indicator on the dash should NOT illuminate.
14. Confirm proper operation of both doors using the dash, B-pillar switches, and the
transmitter button.

And there is some more info in the DIY section of this forum. I forgot that I posted that TSB there a few years ago...
