2005 V6 Mustang Driver Side Door Lock Issue

Good Afternoon All,

Having a bit of trouble with my Drivers side Door Locks. The issue? It doesnt work. When I press the Lock and Unlock button on the drivers side door, the passenger side door locks and unlocks, but not the drivers side door. If I use my auto Lock remote, stil, only the passengers side door locks and unlocks.I Looked at all the Fuses, NOTHING. well, my owners manual actually doesnt have a fuse labeled "Door Locks" ANYWHERE! If there is some secret fuse box other than the one under my hood and near the passenger side floor, can someone enlighten me? Today I took the door panel off to see if there was something that just came unplugged, but everything looks to be in order, it just doesnt want to work. I can get in and out of the car no problem, but I have to use my key..... how Primitive....

Sounds like a wiring problem, but just for laughs, I would unhook the negative battery cable for a while and see if this helps.

If you have a volt meter, put it on the input of the door lock actuator. When you push the lock button you should see a 12 volt pulse to the actuator. If you don't see any pulses, then you could have a wiring problem.

Absolutely check for power, if you have good power going to the actuator remove the plug and check for good pin tension, hate to say it but if all is in good order you will need a replacement door lock actuator!

I agree, that sounds like it is the actuator. Or a wire came loose from the actuator. Have you had the drivers side door panel off for any reason. Like replacing speakers?

They are right, it is most likely an actuator. I had this problem a couple of years ago on my Civic. (POS) Replaced it and it worked just fine
