They do not lock either when you reach 15mph. Interrior lights stay on and message on computer says that the driver door is ajar.

That's why it doesnt work, the switch in the door is stuck, or shorted out.
In order to support the auto door locks and unlock on exit features, if enabled, the power lock system logic in the PDM needs to know the door ajar switch status, vehicle speed, and transmission gear selector lever position. The passenger side front door ajar switch is the only hard wired input to the PDM. The PDM obtains the remaining information from messages it receives from other electronic modules over the PCI data bus network.

PDM(Passenger Door Module).
Door ajar switch needs to be checked!
On Fords these can stick with ages and can be fixed by cleaning the "claw" where the door closes on the pillar. use Brakkleen and spray liberally into the claw, open and close the door 5-6 times and repeat. then use spray white lithium grease and open and close another 5-6 times, this may free up the switch if it's stuck. Works on Fords, may work on Jeep too!
