I drive a '94 Chevy Silverado, and last night, after getting something out of my backseat, the driver's seat would not lock into place or go back all the way. I drove home, took it out, hammered on it some to try and slide it back into position, but it seems that there might be a problem with the roller in it, or whatever it's called. Any suggestions on how to fix it?

 

Probably something caught in the track.....pull the seat out and check it out closer

 

Check for pennies.......had that happen before and it was a penny jammed in between the rails. Them usless things get everywhere...and so do McD's french fries but those don't jam anythinig but your arteries.

 

I took out the seat, sprayed some WD-40 on the slides, looked in it, and am assuming that the roller inside is somehow off 1 position, if that is possible. It is short 1 "notch" compared to the other side each direction so it makes sense that it wouldn't work I believe. Any ideas how to correct?
