I have a 99 dodge ram van b2500.
The driver seat has a manual seat back Adjuster. The adjust still works in the sense that it does still recline, however the angle is super off. In the most forward position, the seat is still leaned very far back. Too far back for me to sit comfortably while I drive. How can I adjust the original angle of the seat back?

 

Look for bent parts.... Or, replace the seat.

 

Mine was like this so I removed the 4 nuts holding the seat down, tilted the seat forward a bit and placed spacers (3/8"-1/2") on the back 2 studs only. I then bolted the seat back down and it was just enough of a difference to make it comfortable. I used spacers that were just thick enough so that the rear nuts allowed for the stud threads to just start showing at the top.
