Hello, My father's 2001 Dodge Grand Caravan started to lose electronic features on its rear hatch door. First the wiper wash fluid quit spraying, then the wiper blade quit working, and finally the key fob and rear door button in the dash quit opening the rear door. It can only be opened manually now. He has checked all the fuses under the hood and the ground wire. Do you have any suggestions? Thank you, Janice
