08 XLT Driver Seat No Power

[Arklelinuke]

I have an 08 XLT that the front seat has never moved since I have had it (bought in 23) but was already in the correct place for me. I incorrectly thought it was missing the seat memory module and went to the junkyard and bought one, and found out the XLT just has the spot for it to fit in but never had that and does not have the plugs for it on the wiring harness. At any rate, on the seat side on the main plug, I found that the grey/red stripe wire was missing its spade connector that slots into the connector. I found it, it was not crimped well, and tried to fix it but broke the connector's crimp wings. Tried soldering it, but it would then not fit into the connector, so I cut it off and then cut the grey/red stripe wire on the other side and spliced in a wire outside the connector (if I understand correctly that wire is supposed to always be hot). However the seat will still not move in any direction. I checked fuse 22 under the hood and it is not blown. What I'm not sure of now, is how to find another flat little spade crimp connector that was not in its place. And since I've bypassed that, what else can I try? Surely both of the motors wouldn't be failed, right?

They never made manual driver seats for the Expedition, did they? I'd honestly rather have one of those than deal with this because my wife now needs to drive this vehicle and is too short for the current seat position.

Here is a schematic for non memory seats.

Awesome, so I guess I've spliced that hot wire together then. I guess that was necessary, would never work without it.

Black and violet ground, maybe should check that next. I'd expect with power that at least some direction would work, and it's more likely I still don't have power yet than all the switches being bad. I'll also check continuity on the fuse even though it doesn't look blown.

Do you have a voltmeter? Should be simple to just check the wiring at different points until you find the 12 volts.

At the advice of a friend, I ran some alligator clips to the motor directly and tested to make sure it wasn't bad with a drill battery to make sure that all of this effort is not in vain, and fortunately, it works. Next is to test with the multimeter and see where I'm losing power.

I did notice one of the 3 motors under there isn't plugged in and doesn't have an obvious plug anywhere to plug into it. It is also different than the other two - the two under there seem to have the pins on the motor side and the cable slides in sideways, parallel to the motor. This other one plugs in perpendicular and it seems that the pins are either missing, or are on the cable side. Fortunately, it is not the forward-backward one, but maybe it is such that they all have to be there for any of them to work (same friend's parents had a Town and Country once that that was the case for). Surely not, given how simple this one is wired because it doesn't have the memory, but could be in the realm of possibility.

I did dig out my multimeter and that is next to see what the deal is (I also noticed my airbag light came on after messing with it the other night - current theory is previous owner disconnected that power wire on purpose to make that light go away if something caused that airbag in the seat to not work - or maybe my bridge wire is not working). Alas, the 9V battery in my multimeter is dead so I'll have to check it later.
