'08 Ford Explorer Limited. Just purchased so I do not know what led up to this problem. Basically, Power locks will lock from any switch. Will not unlock from any switch or with the fob. Just tonight I accidentally got it to unlock(not through the switch) so I know the actuators are working. The only way to get the unlock function to work is by having the key in the ignition, lock the doors and close the door. The lock-out prevention kicks in and unlocks all doors. Brought to to a *shady* repair shop where they charged me $80 and said "it isnt getting a signal to the power junction box" -- which is pretty obvious, and then requested 3 more hours of diagnostic labor to look into the junction box itself. Does this sound like a broken wire between the driver door and the junction box? Does the passenger side switch connect through the driver side before going to the junction box? I know the switch itself is good as I bought a replacement and it still does not unlock. Any suggestions on how to proceed with diagnosing this myself without breaking the bank? Thanks for any input.
