2000 Mountaineer lock issue
 

On my mountaineer i have the keyless entry system on the door. now a few days ago i noticed it would not lock the doors but it will open them, then i noticed that when i get in the truck and put it in gear and let-up off the brake nothing happens, when this is the point where the doors should lock automatically, but they don't.... i think these two issues are related but have not found anything yet, going to check fuses, but the manual has the lock fuses running other items as well, which are still working, and i did not see a relay for it....so now not sure where to go or start...

Thank you!!!

should have a autolock on and off in the setup on the dash, ide try that.
