We have am '05 Eddie Bauer 4X4 expedition with heated/cooled power seats. The driver's seat has not moved forward/back in ages and is locked in the furthest most back position. It has been a major issue and I finally decided to do something about it. All other seat movements work (up, down, tilt, etc.), only the horizontal movement does not. When I push on the switch (forward or back) I can hear what sounds like a relay clicking, but no motor sounds and the seat does not move. I also tried to manually move the seat forward while pushing the button, still nothing. I had read that most others who had this issue needed to replace their motor, so I purchased one and just finished installing it. It came with all of the linkage, motor and what looks like a gear box, but possibly a limit switch sensor as it has it's own wire/plug, separate from the motor.
So, I am posting here because it did not work. After reassembling everything and re-installing the seat (and all 3 plugs underneath) it behaves the exact same. When I push the horizontal seat switch I hear a distinct click, but nothing else. I get this for both forward and backward movement attempts. I double checked all fuses and per the manual the fuse for the motor is shared by all of the other accessories in/under the seat, and they all work.
I tried to manually move the tracks while I had the seat out, but it was locked into the screw gear and I did not see a way to manually spin it (like a nut on one end or anything like that). I would like to confirm that the track is not frozen for some reason. Although I did my best to do a visual inspection and could not see anything lodged in the tracks and shook/tamped the seat and rails to try to dislodge anything that might have been stuck in there. But that seemed to not offer any results.
Is there another limit switch that could be causing a problem?
These are also memory seats, could the memory module be having issues and thereby not allowing it to travel? I felt that was less likely as I could move the seat up and down.
What am I overlooking? I am at whits end and my wife needs to use the truck and cannot drive it like this.
Thanks in advance for any help or guidance!
EDIT: After some more searching it appears that the "little gearbox" that I noted was the seat position/potentiometer (5L1Z-14547-AA). So it shipped with a new one (I ordered from here: https://www.fordpartsgiant.com/parts/ford-motor-assy-seat-adjuster_5l1z-14547-ba.html). It looks like this: https://www.amazon.com/5L1z14547aa-Position-Sensor-Potentiometer-Ford/dp/B0042HHEEM
I checked and the potentiometer assembly is discontinued. Maybe because it comes as part of the motor kit?
