I had a problem where my doors would lock correctly but not unlock. The key and the manual unlocks worked. My rear wiper didn't work either but the washer did. I took it in to the dealer and they said it was the load control module...The fuse box in the engine bay...Turns out there are circuit boards under the fuse box by the electrical plugs. Now that this has been replaced everything works again...I got lucky as I have a warranty and parts and labor would have been almost $900.00.
