Door Locks 1998 Ford Explorer
I have a 1998 Ford Explorer and the left front-driver side door lock does not work using the keyless entry or the door lock button or remote. All the other door locks work. I hooked up a new actuator and the new actuator did not work. I circuit tested the actuator wire clip and power is getting to the actuator - help please.

Have you tried it with the door open? I am wondering if there is a broken wire where it bends in the door jamb.
Make sure you test for voltage at the actuator by reading both wires on the actuator. Do not put one meter lead or testlight lead on a metal ground. There is no ground per-say on these actuators. They are actually little dc motors, and the ground is switched from one lead to the other to reverse polarity for lock and un-lock. So you will get a false reading if you go from a metal part of the truck to one of the actuator wires.

Here is what I did. I went to a parts store and they let me take outside and connect the wire clip to the new actuator. I did not install it, only connected the wire to it and it did not work. The door open or shut makes no difference. The keyless entry makes no sound when I enter the code, but if I also enter 3/4 after my code the rest of the doors will open. Pushing 8/9 locks all doors but the driver side. I thought the wiring in the door jamb was usually if you cannot lock or unlock all the doors.
Is there anyway to rewire from the door switch to the keyless entry and actuator? Sounds like a short somewhere.

I don't have a 98 diagram, but I do have a 99. I don't know if they are the same, but in 99 they had relays to activate the door locks. These are located in the rear of the explorer over top of the driver's side rear wheel. I am guessing you have to take a plastic part of the interior off to get to it.
Whats interesting is the driver's door lock has it's own relay for the unlock function. There are two more relays, a door lock relay, and a door unlock relay. The relay coils are fed power all the time, but are not grounded. The ground wires for the relays run through the different switches in the doors, and the door switches ground the proper wire to activate the proper relay.
