Seat track not lined up?

Are they manual or electric seat rails ? If they're electric then you might need a diagram let us know.
so you might need to take the seat back out of the car, then you need to un latch the truck that's stuck and tap the end of the track with a rubber mallet you'll most likely get them to slide back again unless its been damaged.
If there's a return spring on it you might need to temporarily remove it so it can slide freely (sometimes) there should be a latch there you can retract with a the lever, if not a small screwdriver to release the track so it can slide again. watch your fingers. good luck hope, this helps.

They are electric

Ok look to see if on the bottom by the tracks if theres what looks like a release mechanism locking it in place looks like a metal hook of sorts
Also you can just plug it in and try to control it with the forward and back botons ..somtime it has to unlock when you do that
Please be arful while testing the seat
While I look for a diagram for you

Heres 1 diagram and 1 parts list for the diagram I'm not sure but its think number 24 is the manual adjuster to move the tracks ..to check it out please click below good luck
