The doors are open in my instrument panel.

Door ajar switch problem more then likely or wiring issue . The BCM - body control module won't turn off interior light , let door lock because it think's the door is open . The door ajar switch is a input to the BCM .

The first thing would be to have it checked for DTC'S - diagnostic trouble codes . Also check with an enhanced scan tool to see if the BCM shows ajar switch data (open or closed ? Do you know about body electronics ?

One of your door wiring connections have worn insulation on the connection from door to door mounting area. Typically inside the boot. This problem has occurred on my ford van and it comes an goes. You will probably need to get a dealer mechanic/electrician to investigate the short and replace the wiring harness.
Hope this helps

if you look in the owners manual it will have a listing of the fuses and the location of the fuse box. 6-64

"The fuse block access door
is on the driver's side edge
of the instrument panel.
Pull off the cover to access
the fuse block."

It may be as simple as a failed door switch. It would appear one of the switches has failed "open" keeping the light on and not allowing the locks to lock. Check each switch to see if you can find an issue with one, perhaps the plastic plunger broke and when the door closes it will not open the switch.

Please let me know if this assisted or if you need additional help.

Thank you,
Tom

big job. entire heater plenum has to come out. 6 hour job.
