Wacky door locks

[DWSTANG67]

Does anyone ever had there door locks lock and unlock erratically with car off or on.

It happened driving home from the store than stopped, Then after i parked in garage with car off it started all by itself.

Is my car possessed

That usually happens if you have an aftermarket alarm and water has gotten into the door lock relays but it is possible that the keyless entry module has gotten water in it since it is in the door.

I've seen that happen when the battery is weak.

Mine did something goofy last week-end. When I get out of the car I usually just hit the button on the drivers side panel to lock the car. It worked all the acuators except the one on the drivers side. Pushed the button on the fob and it locked fine. Tried it a couple of more times, same thing. Next day tried it and it worked fine either way. Gremlins at work???

Could be a loose or dirty connection at the actuator or moisture in the actuator.

I realize this thread is several months old, but I just experienced the same symptoms.

First, my MM door locks stopped working altogether from the door panel switches - but continued to work fine from the remote control. The door keypad also was wonky during this time (about one week) - pressing any one button would cause the doors to lock, but if I entered the door code (locking the doors 5 times), the doors would unlock; also some of the buttons caused an unlock to occur before locking.
Then, everything went back to normal. The inner door lock switches started working again, and the keypad also started working normally.
Then, later the same day shortly after starting the car and depressing the brakes, the door locks went all wacky-like, locking and unlocking as if posessed for about 30 seconds (naturally, this happened when I had a date in the car :shake: ). Then silence.
Right now, they are working fine.

While they were acting up, I pulled out the wiring diagram. There's a couple of ground straps attached near the drivers footwell that I was going to check, as well as the 'drivers door module' inside the drivers door. I haven't actually checked either of these yet, so don't know where my problem lies.

Has anyone else heard of or fixed this problem?

They must all be possessed, mine popped the trunk the other day when I sat in the drivers seat... No problem since...

My MM did that too. The keypad had to be replaced. No problems since then.

I'd un lock mine and get in, start it. Put it in drive and the doors would unlock. The exact opposite of what they were supposed to do. I can't figure it out. I have a after market alarm so I use both factory and after market. Now my alarms going off for no reason and my battery's dead.

Sorry not trying to jack the thread. just giving info.:cool:
