Rear passengerside seat belt stuck in retracted position,cannot raise rear seat to upright position. how do I fix it?

When not using the compartment as storage, the read seats can be returned to the upright position as follows. 1. Pull both sides of the seat up into their upright position. 2. Pull down the seat cushion until it is returned to the original position. 3. Return the head restraints to their proper position. You can figure how to raise the Dodge Caravan rear seats by taking a look as to how they are lowered and locked: https://sherrychrysler.com/dodge-grand-caravan-how-to-fold-the-rear-seats/

For some vehicles such as the F-150, other adaptations are possible: https://www.builtrightind.com/blogs/built-x-design-blog/ford-f-150-secret-rear-seat-storage

The likely cause is a broken spring/mechanism in the belt coil. I'm sure you can get a replacement for this belt.

You can't it is not designed that way. The seatbelt mechanism is damaged and needs to be replaced.

Not an easy task. You likely have one of 2 problems. If center seat belt is in the seat that is down, it may be locked. If so, you need to remove the seat back cover then the seat belt retractor. You can then position the seat belt retractor upright (how it sits when the seat is up) and pull the seat belt out making slack to raise the seat. This only happens if the either the stop on the seat belt is broken or the seat belt guide on the seat back is broken. If that's not the problem, you likely have a release cable that has come loose under the seat. If you look at the half that works, you can determine what you need to move on the locked seat and try to get to it with a long tin screwdriver or similar implement.

The problem:
The set belt stop has been lost so the seat belt retracts too far when the seat is laid flat. When laid flat the release mechanism lock as it should when not level. So the seat cannot be raised up as the belt is too tight and locked.
The Solution:
1) Push the two little clips to release and remove the headrests.
Pull the grey lever on the right of the seat base, lift seat base up and forward toward the front seat..
2) See two red capped leversat the back of the two seat hinges and lever them to the upward position, this releases the seat.
Rock the very heavy seat unit upwards and lift complete unit upwards.
3) Take it out of the car and turn 180% so that the back of the seat and base are in the upward position and the seat belt will pull out as it should
4) Replace the missing belt locking stop (I used a tie pin permanently fixed using super glue).
5) Fold seat back down and test then either re-fit seat unit or leave out to decrease fuel consumption..

I just solved the problem for a stuck rear center seat belt in my 2002 Jetta.

Flip the base seat cushion forward against the front seat backs. Trace down along the belt to its tether point on the floor. The belt is sewn around a steel loop. The loop is anchored to a black steel hook. A thin silvery retainer plate is spring tensioned on top of the loop to prevent it from sliding off of the hook when the seat back is folded.

Therefore, you need to press the silvery retainer plate away from the hook (push up) to allow the loop to be slid from the hook. The belt was tight with the seat back in the upright position, so it was necessary to fold the seat back forward to create slack in the belt. Now push the belt loop towards the trunk and slide it off of the end of the hook (only possible with the retainer plate pushed up out of the way).

Now with total release of tension on the system via the bottom end of the seat belt being untethered and with the seat back returned to the upright position, normal extension and retraction of the belt will be reestablished. Next, simply extend the seat belt and slide the loop back into place over the floor hook. It snaps past the silvery retainer plate without all the effort required to hold the plate up during removal of the loop during disassembly.

Check again, the seat belt should be extending and retracting properly. Now just put the seat cushion back into regular position and you will be able to safely buckle up three people across the back seat.

It took about as long to do this repair as it has taken to post this answer to the problem. Note, the seat belt safety mechanism only allows normal extension and retraction of the belt when the seat back is upright.

haha we know you didnt do it on purpose, without seeing your problem and the hard to describe issue, i can only recommend to maybe try folding the seat to the cargo position, if that helps. if not, then you will more than likely need to disassemble the rear quarter panel, and unbolt the seat belt retractor from the body of the vehicle. sorry but there is no other way

anyone have answer for this problem??? i have 05 grand cherokee with same issue.

The fix is:

• remove the seat bench,
  
• unscrew the bolt attaching the seat belt to the body,
  
• return the seat back to its upright position and make sure it latches
• reattach the seat belt
• replace the seat bench

To prevent this from happening again:

• Leave the seat belt latch in its receiver when not in use.
