How to remove a headrest from a S10 Pickup Seat

When you buy new seat covers or want to install a headrest monitor in your Chevy S-10, the last thing you are thinking is that removing the headrest will be difficult. Depending on the year and model of your S-10, you might have a fixed headrest, one that is adjustable by pressing a button or one that is adjustable by squeezing the posts together at the top of the seat. No matter which style of headrest you have, you can remove a headrest from an S-10 pickup seat in about an hour.


      Fixed Headrest


      Step 1


      Release the back of the seat, and fold the seat forward so you can reach the bottom of the back support.


      Step 2


      Remove the seat cover. If your cover is leather or cloth, you will find snaps or a zipper at the bottom of the back-support portion of the seat. Undo the fastener, and slide the cover off. If you have a carpeted board backing your seat, press along the edges of the board to pop it out of the retaining clips, and remove the board.


      Step 3


      Cut the fixed headrest off the frame of the seat body, using a reciprocating saw.

      Step 2


      Insert a small nail into the hole on the side of the plastic base of the support post (which side it will be on varies by S-10 model year).


      Step 3


      Press the nail into the hole. This will release the internal stop clip, and then you can remove the headrest completely.

If you have a carpeted board backing your seat, press along the edges of the board to pop it out of the retaining clips, and remove the board.
