Folding down rear seat in Screw
There are a number of threads and videos on this subject around the forum...but the process is this:
Pull up seat cushion. Remove rear seat headrests.
With the seat cushion up, the seat back comes forward a bit.
Look down behind the seat back and you will see the latch that holds the seat back in place. The latch is located directly below the outside post for the headrest.
A silver pin on the side of the latch needs to be pulled up to release the seat back.
You can get to it with your finger...or slip a box end wrench on it an pull up.
To re-latch the seat back into its upright position, slide the horizontal bar in the bracket on the cab back wall into the top of its slot. This will help line up the seat back latch.
Take your time....watch for sharp edges (I gave some blood when first doing this.)
