How to replace rear-left seat belt?

Assuming yours is the third generation Cavalier, (1995 to 2005), the seats can only be dropped from the trunk. Open the trunk lid and look up at the underside of the parcel shelf. There should be two straps hanging side by side. If you pull the left one the left seat should release and the right one for the right seat. You should hear it release as you pull it. Sometimes you have to push Gently on the back of the seat as you pull the strap to get it to release. Swing the seat belt straps out of the way and the seat should fold almost flat.

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.

Releases in trunk is of no use: no tension/connection therefore cannot engage/pull the cable to release seat to go down. The lever on lower right side of rear right seat won't engage, just flops about.

Hi.

The inertia reel has not been mounted properly. Replacing Toyota belts is quite tricky. Follow the step by step procedure illustrated in manual below. Belts are included in seat removal procedure (clearly do not remove seat). Check chapter starting at page 183/184 in manual below.

Please refer to pages from 184 onward in this service manual.

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 locks 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..

middle seat belt shouldn't have anything to do with it. The seat locks down for stowage in the rear cargo area. you can pull the release handle on the back of the seat to release it back into the up position.

make sure that the rear seats are properly locked into rear catches as this can stop your seatbels from working if ok then sounds like your seatbelt is faulty req new seatbelt.

Best you can do is move it back and forth, pull and release and see if moving it right and left will release it, making sure it is not twisted at the point where it goes into the receiver.

you can remove the bolt that holds the seatbelt to the floor by pulling off the seatpad where the belt goes to the floor and then raise the seat and the belt should reset. this happens on my passenger side rear seat.

your jeep should have all the holes and thread nuts already installed. pull up the carpet and locate them. the two close to the center are for seat belts as are the two outside of them. the four holes that form a large square/rectangular area are for the seat. if your seat is fold and tumble type, holes on the left wheel well are for the locking mechanism. i just pulled mine out and filled the thread holes with new bolts to keep out the water and dirt. yours may have screws or plugs in them. this install is for factory type only. mike
