I've just experienced the failure of the electric door locks and found this information most heplful. First, the lights still flashed correctly when I used my remote to lock or unlock the doors, however the locks did not respond. I removed the silver module that is plugged into the front of the fuse box (actually for about 15 minutes) and then I removed the IOD fuse (it's a 20) that is in the lower front of the fuse box. Imprinted in the plastic is the letters IOD, but they cannot be seen until the fuse is removed. It was held out 10 seconds and then reinstalled as was the silver module. Everything now works, I just had to refresh the menu to get all the doors to open on the first entry (default is drivers door only).
Now I will check with my Chrysler dealer to see if there reaslly has been a recall to update the software. I have owned this car since new, but have not received a recall notice.
