Bad door lock actuator.
Removing a ignition lock cylinder from a 2002 ford windstar with no key
My 2001 does not have a 'lock' button on the power windows - likely because only the front seat occupants have access to the window controls.
check the fuse box
why dont my 2001 windstar van lx door locks wont lock
Your door lock actuator is faulty and needs to be replaced
Having the same problem with mine!
I had the same problem seems that the tumblers for the lock were seised up took it in to get it fix an was out in 15 mins.
Insert key. turn to "run" position. locate "poke hole" on underside of steering shroud. insert tool to depress retainer and pull the lock cylinder out.
the door lock actuator is bad. it is located in the drivers door panel
Anti lock ( antiskid ) braking system
yes, they do on my 02.
check fuses in fuse panel and check , does the power windows work ? , check for power at door lock control unit in door
