May be your switch is sticking open, you can try to spray it will a contact cleaner to see if this helps, if not you can replace the switch or just wire nut the wires together.

2005 Ford E350 Van Door locks & dome lights are going on & off on there own

Do you know anything about automotive electronic's ? Control modules ?
Vehicle Security Module
The vehicle security module receives inputs from the following:
  • Door ajar switches
  • Keyless entry keypad
  • Ignition switch
  • Remote keyless entry (RKE) transmitter
The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the battery saver relay and interior lamp relay. The battery saver relay and the interior lamp relay are internal to the instrument cluster, and are not replaceable. There could be a faulty switch input to the I/C - insturment cluster , causing the vehicle security module to activate the lock's an light's .
Interior Lighting Systems
The instrument cluster grounds the battery saver relay and interior lamp relay coils when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The interior lamp relay then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 km/h (15 mph) for the instrument cluster to ground the interior lamp relay. The interior lamps remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster receives an input from any of the following:
  • voltage from the ignition switch.
  • a vehicle speed signal.
  • input from the keyless entry keypad through the vehicle security module.
  • input from the RKE transmitter unlock or panic switch through
  • the vehicle security module.

Door ajar light stays on as well as interior lights when all doors are closed

Most vehicle door open light works by a spring loaded contact switch. The switch body acts as ground. when the door is closed the switch depress disconnecting positive from ground. Seems that one of your door switch may be bad. Look for a rubber covered sitch on the door jam you should be able to remove the rubber cover to access the switch for a good inspection.

When my "door ajar" light was on it was because the liftgate sensors (switches) indicated that the gate was open, even thought it wasn't. I took off the plastic trim, and took out the sensors - but that isn't necessary. Just soak with the switches with silicone spray, and see if that helps. There is one on each side of the liftgate - I believe both must indicate "closed" for the light to go off.

I have gotten replacement motors at Checkers for both driver and passenger doors - so now I have lifetime replacement motors.. The first time you replace them, a little drilling is needed on the door sheet metal, but it will not show up once the trim is reinstalled. This repair is a little involved, but well within the capability of a novice mechanic.

Door ajar stays on usually when it rains

Try opening and closing all four doors one at a time to determine which door ajar sensor has failed. Probably driver door. Sensor is located in door latch assembly and is a challenge for first timers. This is a common problem with these vehicles.

The security system

Have you found any evidence of mice, turds or nests? Mice love dormant vehicles, although they usually move into the heater box. MIce love to eat the insulation off of wires. A bare wire could cause the door ajar to stay on, and may have burned the timer out of your auto lights. Have you checked the battery in the key fob? Sometimes you can just clean the battery and contacts. You have two fuse boxes one inside and one under the hood, the one under the hood also has relays in it and you want to check those out to. You may have one stuck on or inoperative. Look at the wiring harness all over for a poor ground connections. Poor ground can cause power to back feed through other components, making them suspect when the problem is elsewhere. Good luck, CB
