My passenger power seat adjustment wants to move on one side of track but not the other. It won't move forward or backward and doesn't seem to have an obstruction. Any remedies? Thanks,

 

welcome on a board !

if the power seat doesnt't work, put the seat back section of the seat down to it's lowest position a couple of times. This somehow resets the body module for the driver seat. Weird but it has worked several times for me.
