Power door locks not working. when you press the lock button you can hear the clicking from the relay by the fuse panel but locks do not move. also when you hit the lock button upon exiting the vehicle you hear the 3 bongs but the doors do not lock when you close the doors.

Improper (low) voltage at the actuator solenoids. Could be poor frame ground or possibly an issue with the BCM.

The relay makes a clicking noise when you press the lock button it's not the relay that's the problem. You may have a bad lock motor or what it's called a solenoid. When it's energized it moves. The problem is the get wet or dirty they jam up and stop working. So if you know for sure it's getting power or not getting power. Could be the lock switch could be the issue also. Removing the door panel and test the solenoid first to make sure that works then can test wires or fuses.

By CLICK do you mean the normal sound you are used hearing and I'm asumeing you are talking about the keyless entery.
Do the other doors lock and unlock normaly.
If so then the problem is inside the door .The way it works is their is the motor that moves the mechinisum that has small metal rods that have clips and plastic anchors that will pivit somewhat .
However some times with the window partitaly down at highway speeds the window can move out of the track it runs in and hit these rods if rolled all of the way down witch could a clip to fall off the rod . Or one of the plastic peice could have broken
In short if the other door locks work their is no problem with the keyless system but a broken or disconnected part inside the door that isn't working.And needs to come apart to know for sure .

There are some mechanical rods in the rear hatch that are probably rusty and you will have to take the inner panel off to acces and clean them to get them moving to operate the lock.

If the horn fuse ( Fuse #26 ) is installed and has power on both sides of the fuse, you might want to check that the horn connector is still on the horns.

The horn relay is not serviceable in the fuse panel.

You can test the horn connector for power, the Yellow w/ Light Green wire, when the horn button is pressed.

you have a bad relay.. the 'lock' relay.

first thing to check is the wireharness under the passengers floor mat,you wiil probably find a mass of corrosion and bad connections,been there done that!

Hello, I had a similar problem. I checked the fuses dr unlck 10amp, dr lock 20amp, both fine. However, I finally had no choice and checked all other fuses and the 15 amp fuse labeled "CTSY" was bad! So, check that fuse. If a similar problem has happend to you, it could be all you need.
lol

Try replacing the relay. Clean the socket of the relay and fuse

I had almost the identical problem on my 2005 F150 FX4 Extended cab last weekend. The power door locks would not lock using the keypad, remotes, or door buttons. Almost all other functions worked correctly. The doors unlocked, the radio delay functioned, and the interior lights dimmed. When I used the remote the horn would beep twice indicating that a door was open even there was no message on the message center that a door was open. When I used the keypad or remote, I could hear a soft click from behind the seat. I think it was coming from the body security module or body security module - whatever Ford is calling it this year. I pulled the fuse for the Power Door Locks(BSM). As I removed it, I heard a soft click - sort of like a relay resetting. It may have come from the VSM/BSM. It may have possibly been a stuck actuator releasing. I don't think so. It wasn't that load. In any case, everything is functioning correctly now.
