Searched around here but never saw any aha! fixed! threads.
My door locks don't lock electronically any longer. I can hear something going on, and it sounds like the battery is weak like a motor is struggling to lock. However the battery is fine. I've pulled the Door Locks fuse as well as the accessory fuse.

An issue that started today as well and apparently was solved was the Aux. power shutting off when the truck is shut down. For instance, the radio will stay on until the door is opened. I am not sure if pulling and re-seating the fuse had that effect or not.

There sounds like another relay or solenoid somewhere in the center console area. Anyone know exactly where that is?

The drivers door lock operates fine using the key, passenger side is electric only. Don't think there is anything in the door that's bound up.

Any pointers would be appreciated.

The issue with the AUX power turning off when the door opens is back. I think fuse 22 is the common connection there. It's not blown, so I am stumped.

Door locks still sound like the battery is almost dead when they will activate. Battery is strong, so maybe there is a wire shorting in the run from the body into the door at the door hinge.

 

Now the DOor Ajar alert is staying on constantly and the headlights are as well. I hear what I think is a relay going crazy behind the rear seat.
Anyone know which fuse is controls that? The timer that turns off the lights must no longer be tripping.

 

I'm thinking the Body Security Module may be the culprit. Pulled the back seat and noticed some water on the unit and down in the floor. I guess it came from the 3rd brake light.
I loosened the grounds and sprayed some contact cleaner on them then re-tightened, but no luck. Also pulled the plugs going into the BSM, contact cleanered them, and re-seated but no luck.

If I buy the module, do I have to get the dealer to program the key fob, and keypad to work?

 

SO it is a leaking 3rd brake light that killed the BSM. The masters at the local dealer took all day to diagnose it and of course didn't have the part in stock.
So thanks Ford, yet another case of sub par quality. Add this to the driver and passenger window regulator that died at year 4 then year 5 as well as a failing MAF.
