Why? is the door ajar light lit? No fuse or relay. Is a function of the SJB - smart junction box, ford's name for a Body control module. Door ajar switch is wired directly to the SJB. Hooking up a scan tool to check for codes would be one way to find which door switch is the problem . or watch the videos ,could just be stuck an needing cleaning. WD-40 an rust penetrant.
You replaced lift gate ,with a used one ? Did you replace door ajar switch with new one ? An what's this ovedrive ? Do you mean overdrive light ? If so the door ajar has nothing to do with that . When that light comes on you have a transmission problem .
The door switch doesn't go to the dome lights , the switch (door ajar switch ) is an input to the SMJ - smart junction box or body control module take your pick . Principles of Operation
When the SJB detects a request for lighting, it turns on the interior lamps by supplying power to the lamps. The request for lighting can be an open door signal from a door ajar switch, an interior lighting on command from the instrument panel dimmer switch or an unlock command from a remote keyless entry (RKE) transmitter.
The door ajar switches are hard-wired directly to the SJB. The 2 door ajar switches are normally closed when the doors are closed. The decklid ajar switch is normally closed when the decklid is closed. All door ajar switches receive voltage from the SJB and each has its own ground circuit.
The instrument panel dimmer switch receives a ground signal from the SJB. The instrument panel dimmer switch provides variable resistance for backlighting the instrument cluster and a toggle ON/OFF function for the interior lights.
The RKE receiver is contained inside the SJB. When the SJB receives an unlock request from an RKE transmitter, it unlocks the doors and turns on the interior lamps. There could be DTC'S diagnostic trouble codes stored in the SJB ! You can not access these codes with a OBD2 code reader , need a factory scan tool .

door sensor is bad. switch is staying closed allowing juice to interior lights. The door switch is there. have autozone or napa look up the location for you...
make sure the seatbelt isn't getting caught in the door jam when you close the door, it could be enough to keep the door slightly ajar or.............. when you slam the door it's possible that another door/hatch could be popping open slighlty if the latch on that door is not 100% holding tight so check each one....good luck
The door sensors have to be adjusted my 2001 ford Ranger and 2008 ranger had the same problem aslo almost all of Fords cars have an issue with the adjustment not staying adjusted. you will have to find the door sensor and screw it if far enought to get it to make contact.
There is a "switch" inside the door lock ...it has small ball at the end that retracts when the door is closed.
You can either replace the switch by removing the door panel and get access to it (follow the wire) ...or you can access it thru outside of door lock with small and long scredriver and free the ball with some lubricant.
The doorlach pin is faulty.
On newer vehicles it is inside the door on the locking mechanism.
It is stuck in the closed position, or has become dislodged.
Refer to your mechanic for repair.
