My problem is like many others I have read about the "Door Lock Problems" on the Explorers. It started to fail every now and then, then quit all together. I can lock all doors from the driver's panel, but not unlock any doors from the same switch. Yet the passenger's side will lock and unlock all doors. The back switch at the hatch works fine also. The only one that can't open the doors is the driver. I have keyless entry that also works all doors perfectly every time. The last time I had the truck in the Ford dealership, they replaced the door control panel, it quit working a few days later again. Tonight on another Explorer Forum, I found a post that sounded exactly like what I have going on. After looking in the area they told me to look, it was the same fix. Here it is: 1. Open the drivers door and look at the boot connector that protects the wiring from the door to the truck. 2. You can take the cap off the top and undo the long screw that holds it together , or do like I did and cut the tie wrap and slide the boot down a little. 3. look in the bundle for a broken wire. I was surprised to find one in mine just where they said to look. Conector number is C-245. The wire colors are for the LOCK funtion Pink wire with a GREEN tracer. UN-LOCK wire is a PINK wire with a YELLOW tracer. There is not much slack in the wire but I got enough to solder the two wires together and cover the splice with a peice of shrink tubing. Sliding the boot back up and putting a 1/8 wide X 8 inch long tie wrap back on it to keep it water tight. Problem fixed for under $2. I hope this is helpfull to somebody , as it was for me. My next step was to put an expensive "Keyless Entry Computer" (RAP Module) in. GOOD LUCK!
