Check the contact device on the door jam. It should be a spring loaded switch that should close the contacts when the door is open and open the contacts when the door is closed. Sometimes the contacts can become corroded or just dirty (usually from oxidation of the metal) Once you have removed and cleaned the contact terminals with a wire brush for the switch check and see if you still experience problems. If you do then it is most likely a short in the wire from the fuse box to that door (or possibly a bad ground, you will just need to follow one of those wires to see where it grounds on the body or you can just check with a voltmeter to see which one it is). You can easily differentiate between bad contacts at the door or a wiring issue if you short the switch wires to on and see if it stays on. If it stays on then it is the contact switch on the door jam; if not then it is the wire to the door.
