Drivers seat back will not lock in upright position

Hello Friend:

I use to own The Same Vehicle:

#1) Check the Release Handle to See if its Mounted Good and Tight:

#2) Take a Close look at the While Pulling the Release Handle and Let Go to see if it Returns to the LOCK Position on its on.Its Spring Loaded to Return after you Raise Seat to Lock into Place on its own by the Spring.

#3) Check on Both Sides on Each Step. And Make sure theres nothing under your Rear seat Stopping it from Functioning Properly.

#4) If all thats working and its FREE of Obstructions.Then take a Close Look at the Metal Catches on Both Sides, Check them make sure they are Both Securely Mounted.

#5) Now look to see if they are worn out so much that they Just don't Hold the Back of the Seat up anymore.If they look worn or Bent Replace them.

#6) Also check to make sure that the Pins or Bolt Catches are Tight and not Worn.I found out that if when Raising the Back seat up if you Don't Use the Handle that Releases it it Will Eventually Wear or Bend the Hook like Catches and the Stationary Locking Pin out.

This should get your Seat problem Solved just Check each Function of the Back Seat Catches as Described above.
