I have just bought a used 1994 Ford Explorer. I find that when I put the key in the ignition, about 3-5 seconds after I move it to the ON position all the doors lock. Further, as soon as the ignition is moved from ON to OFF (or Accesory), all the doors unlock.
I consider this to be a bug, not a feature. I wish to prevent this. I have the proper Chilton manual, but it doesn't cover this system. I have looked through Google, both for the web and for newsgroups. I found a method requiring repeatedly switching for ON to OFF and pressing UNLOCK. This does not work on my car. I suspect this way of "reprograming" whatever module/device is reponsible for this bug doesn't work on as old a car as mine.
This car does not have a keyless/remote system, nor any kind of keypad on the outside.
Does anyone know a "reprograming" method that will work on a 1994 Explorer?
Failing that, does anyone know what/where the module/device that does this is, and if I can wire around it, without disabling something useful? I have located the fuse that (supposedly) runs the electronic door locks. Pulling that fuse does prevent the controlled opening/closing of the locks, but the automatic open/close still occurs.
If there is no wire-around, what is the best way to disable the electronic door opening/closing mechanism? Frankly, I would rather have mechanical-only door locks than having them lock/unlock out of my control.
Thank you for your time. :-)
