Diagnosing Power Door Locks

courtesy of Bob, The Auto Answer Man

Dear Bob,
Our Taurus power door locks suddenly have stopped working, is this an expensive problem to fix?
Andrea N.

It depends on the cause. If it is a bad fuse, then no. If its a bad switch, then it may cost a bit more. If you bring it somewhere, you will probably pay more in diagnostic than anything else. Look in your owner's manual for the location of the door lock fuse. Check that out first. If that is fine, then you need to determine where the actual fault is. Do the door locks work from either side or nothing at all? If nothing at all, then it would seem more like a power problem than anything.

If one door works, and the other does not, then I would think that there is a problem related to that one side. Can you unlock both doors from one side? Can you unlock the good door from the bad side? If one door does nothing, and the other door can operate both, then it seems the bad door has a bad switch. If the bad door can operate the other door, and the other door can not operate the bad door, then it would seem like a bad actuator in one door.
Good Luck!
Drive Safely!
