Interior lights stay on and car is dead on 95 Deville

Interior lights to my 95 DeVille stay on after I close the front driver's side door. Need to open and close it several times before light goes off. This morning everything was totally dead and I had to attach a battery charger. Any ideas where the short may be coming from? Also, cannot open all 4 doors forn either driver's inside control or remote control :frown: (have replaced battery in remote). However, when I manually open one of the rear doors, then the remote will open the remaining locks. :eek7:
