I have a 2008 Grand Caravan with power assist rear doors. One day this past week, while the door was activated and closing it suddenly stopped about 2/3 of the way closed. I was able to force the door closed to get home. (I saw nothing that blocked it from closing, even along the top or bottom guides.) The next morning, the van would not start. I jumped the battery, got it started, and then the rear door motor seemed to be disengaged, and I can manually open and close it now. (I've had no starting issues since, and the battery is less than 6 months old.)

Now, the door has no power to the power window, heated seat, or to close or open the door from the remote, or either of the interior buttons. The power lock DOES work, both from the remote, and the driver's door panel. Also, if I open the drivers side rear door and start the van, it does not acknowledge that the door is open.

I have checked every fuse in the fuse box, and found none that appears to be blown. The passenger side rear door, window, and heated seat are all working fine.

Any ideas what is wrong??

 

You'll have to inspect the power door wire bundle in a cavity next to the bottom of the door. Here's what you're looking at:

 

Thanks! I had no idea how to access that line of wiring, so this looks very helpful!! I'll give it a try.
