I have a 2001 Ford Exlporer Sport. None of the power door locks work including the 3rd door. They all went out at once. Someone said it might be a relay. I looked in the owners manuel but didn't see a relay dedicated to all of the power door locks. I checked the fuse for the locks and it was fine. Has anyone else had this problem and found a solution?

Might want to pull the door panel and be sure the cable connector to the switch assembly hasn't come off.

There are a couple fuses and relays to check, and also the CSM (Central Security Module - less likely that this is the issue...) . Look for simple things first.

From the Ford diagnostic charts:
Power Door Locks
The central security module controls the power door lock and keyless entry system. The lock and unlock operation is carried out by supplying ground to the central security module from the door lock control switch. The normal path of the actuators is to ground through the central security module. The door lock control switch will lock and unlock all doors by grounding the appropriate circuit to the central security module. The central security module then supplies power to the appropriate common actuator circuit to lock or unlock all doors.

CMOS,

Thank you for your help. I looked briefly at the vehicle last night. The Explorer is my daughters. There is no key fob or keyless entry. I did find out that the 3rd door lock works to unlock all of the doors, but not to lock them.

I looked through the owners manual again and didn't see any fuses or relays that are specific to central security or a central security module.

Since one lock seems to work somewhat I am thinking of looking at the lock actuators as outlined in another post on this site.

I did pull the driver door switches up to make sure the harness was securely fastened to the switches. That checked out.

Thanks again,<O

You need to check the wires in the driver door accordian, they are under stress and fail.

 

I will check them out.

 

Common, have repaired many, if you find break, add cple inches to wire, solder and use heat shrink

 

Do you happen to know the gauge of wire?

 

multi strand, some 10,12,14,16 dependant on the circuit

 

Mine just did this two days ago. All of the doors will lock with remote and manual switch, but nothing will unlock them exept the key or pulling the lock up by hand. Hope to hear more about this. Im going to try and check some relays tonight and cable connector.

 

Your lock problem sounds similar to mine (2003 F150, Crewcab). All my locks quit working at once, however, the drivers side will unlock with the remote but not lock. All the door switches don't work (lock or unlock) but I can hear the clicking at the security module, same when using the remote. My repair manual (Chilton) addresses what to do if you don't get the click but does not say what the problem is if you do get the click.

Have you had any luck with your locks? Do you get the click at the security module? Anyone have any ideas?

Thanks,
KW

 

Have the same problem 2001 Explorer Sport -key fob works to unlock all, but cannot lock with fob or switches.
Door switches inoperative (neither lock or unlock), third door switch unlocks all but does not lock???

The fuses are all good, wiring connectors all connected.

Any one have a schematic, I have wiring diagram and shop manual, but difficult to trouble shoot without schematic from here on; without removing components and "easter egging"

 

Welcome aboard reoal. Aquanaut is correct earlier in this thread when he said it's common for a wire to break in the driver's door accordian conduit. It is usually a ground wire and that causes the solid state relays in the security module to malfunction. Often other items controled by that module also start to act up, like the puddle lamps and door ajar lamps.

 

I know this is an old post but my 01 f250 has just started doing the same thing. The relay is still working but the door locks are very very weak and will not open. I've not torn open the door to check it as I've just learned that it may be the wiring there.

The door locks stated failing slowly at first now now the relay just clicks and the door locks barley move at all. You can still hear them wanting to move but it's like the current for them to operate normally isn't there. Going to tear into this tonight but wondering if anyone else has any ideas.

 

I have kind of the same problem on my 02 4.6L explorer XLT I went to lock it up the last night and the hazards came on with a loud tick that I could hear from the outside. I could not use the remote or the inside switches to lock the doors tried to start the truck but nothing. This morning I checked the battery with my multimeter it read 11.4v the battery is now charging. We just bought the truck privately and I suspect it is the original battery in it. I will see if it holds this charge, if not it is off to the dealer for a new one.
I HOPE IT IS THE BATTERY AND NOT A WIRING PROBLEM!!!

Cheers.

 

Can you freely turn the key lock switch in the door? You could also have a scenario where the lock linkage is gummed up and putting extra strain on the the power lock motor.
