My passenger seat is locked and cannot move forward or backwards. I just let the dealer checked it and was told that the rail is broken need to replace it which cost me $900. it is alot to me. I am just wondering, For this kind of 2Door Car. the seat is manual seat. it should be very simple device, and I didnt find anything wrong when I took a look on it. I checked the rail, there is nothing on it. no coins, no any obstacle.

Can anyone tell me how should I do next? should I just remove the 4 bolts of the seat and take a look on it?
