Auto door locks? Reply #15 – January 25, 2008, 09:21:21 AM Yeah, well...that's according to Ford's instructions anyhow. Maybe it was a feature that they planned on adding but it seems they never did. My Mountaineer doesn't unlock (but it does auto lock), and it's 10 years newer than these cars.Tom, do you think maybe there's part of the keyless entry module that would support the auto unlock feature? Maybe something's there, just disabled. That might be a good project for you guys with keyless entry... Quote Selected
Auto door locks? Reply #16 – January 25, 2008, 09:52:13 AM There would be no need for an auto unlock because of the function of the interior door handles. Even the brand new Mercury's on the lot here don't unlock. But you can pop the trunk from the key pad :hick: Quote Selected
Auto door locks? Reply #17 – January 25, 2008, 05:39:56 PM I tried the code with no luck but I havent gone any further as to look under the seat for that plug. I do know there is a harness under there that I think goes to the seatbelt? that has the wires pulled out of it but I dont think this has anything to do with the auto lock feature. does anyone have a wiring diagram for this?

Auto door locks? Reply #18 – January 26, 2008, 11:54:26 AM It's under the seat near the power seat harness. It connects to a sensor under the seat cushin (looks like a long aluminium strip with a plug). BTW it's a PITA to plug and unplug because the power seat track is heavy. Ask me how I know :hick: Quote Selected

Maybe I'll kook into that one of these days...Wasn't the auto lock feature's activation/deactavtion default reversed from '87-'88??? Seems I remember the feature defaulted to on if the system lost battery power and to off in the '88s??? Maybe I'm dreaming???? I know the '95 didn't loose the secondary code when I had the battery out for approx 20min awhile back... Quote Selected

When the shifter is in transit passing "through" the reverse detent, there is wiring in place that operates the "Lock" function of the doors. It is like pushing the lock button since you are in reverse for a fraction of a second if you go directly to D. Now if you select reverse, the same happens but I would suspect that the door "LOCK" solenoid is being powered /grounded for the entire time you are in reverse. The engineers probably decided that no one would be in reversee for any extened period that would exceed the heat disipation of the solenoid shell/windings.BTW,, tke keyless entry does have pins dedicated to the "UNLOCK" funtion. so here is the senerio.......doors unlockedcar offinsert keystart carclose doorgo to D (passing through R)doors lock.What i plan to do tomorrow.with car on door lockedcar in PI will go to NI will unlock doors by the buttonI will put the car in DThe doors should remain unlocked.I will accelerate and verify that the car speed sensor does not also lock the doorsIF the door locks remain unlocked , this would tell us all a lot. First off we could not just duplicate this circuit type within the "N" becaue you would unlock your car as you pass from D to N but upon landing in R on the way to P, your doors would lock again.I would propose duplicating this "unlock" function two wire circuit in the ignition switch. here is the theory......You pass through "R" while the car is running and you drive along.doors just lockedYou stop your car and turn your ign switch back to the lock position (where you normally would take the keys out)You should have power waiting for you there on the ignition switch from "OFF FUSE 1" that could be applied to "UNLOCK" funtions of the keyless entry pins 1 and 3. I think that when you land on the "OFF, you will get enough power to the unlock pins 1 and 3 but then it goes away when the car finaly shuts off which is a good thing.Now all we need is a logical ground.

Auto door locks? Reply #21 – January 27, 2008, 09:42:36 AM another question before I pull my seat, was auto unlock an option or was it standart equipment in all of our cars? I found a harness unhooked and sticking through the carpet but I didnt find the one coming from the seat its a two wire harness with a solid white wire and a solid black wire no stripes on either wire. or is it possible that I tucked the seat harness up in the seat track when i put the seats together? maybe I should just pull the seat anyways Quote Selected

Auto door locks? Reply #25 – January 28, 2008, 03:50:25 AM so uh, why would our cars want to know whether there's someone in the seat before doing the auto-lock? Quote Selected

Can be a pain in the ass if they want to get back in in just a few seconds... Quote Selected
Auto door locks? Reply #27 – January 28, 2008, 07:07:42 PM On mine if I shift into park (with the car running) after the doors have auto locked and then open the door with the handle (with out hitting unlock) the door unlocks and stays unlocked even if I shut the door. The door won't relock untill I sit in the seat and shut the door. That's what the weight sensor in the seat is for. Quote Selected
Auto door locks? Reply #28 – January 28, 2008, 11:11:35 PM the reason I asked is because the car I got my seats from did not have keyless entry and I cannot find the wiring for the weight sensor. when I get a chance I'll look at my old seats and see if it might be something I can add on to my new seats.

Have fun getting it out and into the new seat (you have to take the lower seat cover and cushin off:hick: ). Quote Selected
