door lock issues

[At1Maverick]

One thing I haven't tried to tackle in my 95 GT is the lock issue. First off, it was given to me knowing that the key doesn't work for anything other than the ignition (likely from whatever accident it was involved in previously). The other problem being that the passenger door seem to be possessed, when trying to unlock using either switches, it immediately locks itself. I can open the door from inside using the handle only. I haven't tried replacing the switches but I pulled the panel and looked into the wiring and saw nothing out of the ordinary. Is there a link on how to diag this problem? Thanks in advance!

its called a 5-wire reversing polarity system and its great for ford as it has no relays, sucks for us to troubleshoot... A bad connection anywhere in the loop will make them act strange, sounds like you have a bad connection on the unlock button but its hard to diagnose in person, let alone on the net.
