Power Door Lock ????
OK - I am stuck on this one, Please Help --
97 Explorer - Driver side door switch will lock door but will not un-lock, however the pasenger side door lock switch both locks and un-locks as it should. I have replaced the driver side door lock switch, but no joy - same problem will lock but not unlock. Sugestions please.

I am looking at a 96 diagram, but it might be the same as your 97. Let's see if it is.
There is a door unlock relay. There is a pink/lightgreen stripe wire that goes to this relay. Anytime this wire is grounded, the unlock relay is activated, and the doors unlock.
I would hunt around the driver's side kickpanel, and see if you can find the pink/lightgreen wire were it comes from the driver's side door. If you find it, stick a pin in it and ground it out to see if the door locks unlock. If they do, I would work my way up into the door, and ground the wire out and see if the door locks unlock. Somewhere along the way, this wire must be broken. If the switch you replaced is easy to get to, then you might want to try grounding the wire at the switch. Possibly the ground wire going to the switch may be broken.

The lock switch at the rear is wired directly to the relays (also in the rear). Do the locks work normally from that switch?
As Dave mentioned pink/light green is wired from the unlock relay to drivers door switch.

OOPS, you did say the locks work from the passenger switch.
The passenger & driver switches are spliced together at the drivers side rear wheel well.
So pink/light green is open somewhere between the splice & drivers switch.

Thanks
Thanks
Hope this is clear - hard to describe - it is my Son’s truck and it is not here. I do need a diagram for 97 Explorer or color code for wires at lock switch.

The first thing I would do is pull the switch back out(if it's easy) and ground the pink/lightgreen there. I don't know how they ran the ground to the switch, but if they did something cheesy like get the ground from were the switch is mounted, and there is something wrong with the mount, then it may have lost it's ground connection. If the pink/lightgreen won't work at the switch when you ground it, then it must be more serious and you will have to start digging. I would think were the wires bend back and forth in the door jamb would be a likely place to look.

On a 97 the only connection between the drivers & passenger switches is that splice that I mentioned. Your 87 wiring diagram is a different setup.
I have the 97 wiring diagrams, but no way to post them. Strange thing about the diagrams is they show unlock (pink/yellow) at the switch wired to the lock relay. And lock (pink/light green) wired to the unlock relay. Go figure.
From other posts that I've seen the most likely place for a break in the lock wiring is under the rear seat/driver side or, more likely where the wires flex everytime the drivers door is opened.
I've never done it, but the "barrel" that the wires pass thru at the drivers door can apparently be opened up to check the wires.
Hope this helps.

The switch has 7 (seven) connections - am I correct that 2 are power and ground for switch light and the other 5 connections provide functionally.
I will be out of the country for the next 2 weeks starting 5/19. Thanks for the assistance - however, I am having a difficult time with limited info. Please keep it coming though.

As they say a picture -or in this case a wiring diagram- is worth a thousand words.
Try this draw a large Y on a sheet of paper.
Where the 3 lines come together write the word "splice"
At the top right side of the Y write the words "passenger lock switch"
At the top left side of the Y write the words "drivers lock switch"
At the bottom of the Y write the words "door unlock relay"
All 3 wires are color coded pink/light green.
Somewhere beween the splice on your wiring diagram & the drivers lock switch that pink/light green wire is broken.
All the switches do is ground the voltage coming from the coil side of the lock/unlock relays.
This closes the switch side of the relay & sends voltage to the door lock actuators.
Not that it matters in this situation, but the door lock relays are in the jack compartment at the left rear of the truck.
