power passenger seat will not move fore/back

[mervincm]

Factory leather+electric option seats. I am the original owner and the seats have never been serviced to my knowledge. E82 Canadian vehicle.

Neither the floor nor the head-rest control work. The remaining electric seat controls work fine, I can raise/lower, and adjust the tilt angle. The only problem is moving it forward and backward. The seat is stuck at the rear-most position and when I use the floor area control and repeatedly press it forward you can feel it "try" but no actual movement forward.

Any ideas are appreciated.
(First post, be gentle I did try a search!)

If you can feel it try.... hmm. Either it's stuck, like a mechanical issue, or the motor's bad and not strong enough for some reason to do anything other than make a little noise.

I'm not familiar with a head rest control, so - if you think there are multiple motors out at once, then it sounds like a wiring issue. Corrosion, pinched, fell off, etc.

Might be time to open up the seat.

Ya there is sort of a click noise, like it tries. I have not noticed any motor labouring, it was previously nice and smooth. It’s a clean car less that 40K km on it, summer driver and never had a window left open in the rain or anything obvious like that. The screw rods that seem to there to power the seat forward are not gummed up, dirty or corroded. My apologies but I was unclear on the top controls. They are just a second set of controls that allow you to move the seat back and forth without bending over, they are not a separate motor.
I may indeed need to pull the seat, see what there is to see .

If not done already, get in there with a small flashlight and look all around. Even a 25 cent coin can jam forward movement.

This was it. A small piece of a COVID mask was caught up in the motor. I saw it the first time, but it was really tightly wrapped and looked like it was supposed to be there. I finally compared it to the driver-side and noticed the difference.

That said, even though I identified it, I was no closer to solving it. Without access to the seat fastening bolts, I could not remove the seat to get at the problem. it took two days of lying twisted on my back for as long as I could stand it to pick away at it enough to finally clear it out. In any case, it is now fixed!! Thank you very much.
