when you get the panel off, you can see that there are 2 or 3 sets of wires, 1 of them will only be one wire with a connector on it, just pull that off and tie it back so the window doesnt get it when you roll it down.
i know that this wire is for the door ajar light because: my passenger door lock was sticking sometimes unlocked, sometimes locked (not allowing you to open the door). i found that the latch assembly was jamming up with the help of the power lock actuator. so i found a taurus GL at my local j/y with power looks and grabbed it. i noticed while installing that it was missing a section, and had no where for this one wire to connect, so i tried and sure enough all works except for that dash light (it stays off full time...only regarding that door, works on all others)
