2005 Ford Expedition XLT, major electrical problems

Could be the electric lock actuator . Without testing this would be just a guess. Video's on youtube showing how to test .

Try going to the Expedition Forum, where other people had the same problem: http://www.ford-trucks.com/forums/1022050-all-power-door-locks-dont-work.html


I hope that helps!

Check for blown fusible link that supplies switch.

Will the switch on the door lock or unlock the doors, if so check the battery in your remote, it may be dead. Remove the key remote from your keychain and there is a slot in the end of the remote that will open it up so you can gain access to your battery. Pay close attention to the way the battery is installed before removing it. Replace the battery and try the door locks again. If they work, then you have solved the problem. If not, you have an electrical problem that you will have to trace down. From the information you have given, this is all I can tell you without seeing the car for myself.

I wish you luck, I hope this helps you find the problem.

Ck the window power or door fuse , they sometimes slave remote relay off them. Mult use fusses tick me off. But when you get used to it, they can help u trbl shoot.

Undo the battery to reset the computor.

please rate as solved if this is what you need. You will need to borrow a heavy duty riveter from autozone or wherever you buy the lock cylinder from.

Hope I was avle to help, glad you up and going.

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.

I have an expedition with the same problem.To fix it just spray some PB blaster on locking mechanisms.WD 40 works also but may melt the wiring harness.I used wd 40 and I have had no problems since. GOOD LUCK.
