Chevy uplander back seat wont go up

Mechanism most likely broken . I had a Hyundai and was rear ended and the mechanism broke plus I know of several other seat backs that broke on people

The gears for the recliner has been misaligned/broken. Disassemble and look for broken parts. Refer to service manual to realign,

Will it latch if you push the release handle down, you know opposite of trying to get it to release? It might be a broken or dislodged retaining spring that pulls downward pressure on the release handle. If this is not the problem then the teeth on the gear that the release handle engage are possibly worn out.

The locking mechanism on the rear lift gate for the Chevy Uplander has some plastic and rubber-coated parts that can get jammed. If you can pull back the panel from the inside top near the glass, you can reach down and try to spray some silicone lubricant into the lock. This could help get those parts unstuck so they spring back when you pull on the handle latch from the outside. Once you get the rear hatch open, I recommend taking out the locking mechanism and thoroughly lubricating it. Your rear lift gate will start to release very easily from then on.

i had this problem on my 96 chevy, basically theres a set of ratcheting gears that lock the seat in place in the various positions. sometimes over time or due to abuse one side or the other gets stripped out and the seat will no longer lock into place. i found a ripped up seat on Craigslist that was in a part out truck and bought it cheap then took both seats in the an upholstery shop, between the junked out seat (15 bucks) and the labor at the shop (50bucks) it cost me 65 bucks to fix, hope this helps

Under the seat there is a spring that conects the 'handle'to the Latch, tha tholds the seat in place....you will have to look under the seat to see if the spring is broke

Okay so im just going to start from the seat being upright in a normal riding position.

1. You need to fold the head rests first. Pull the black tab under both headrests. They should spring into a folded position.

2. pull the side seat lever (on the door side of the seat). This will fold the top/back support down to an angle.

3. There is one more lever on the backside of this seat. Its in plain sight on the angled portion of your seat. Lift the big plastic lever.

4. While keeping the handle lifted, grasp the back of the seat and pull it torwards the front of the car. The seat should come unlocked and roll forward and down more towards the floor. If you have a bunch of junk on the floor, it obviously wont work. clear the path and the seat will fold completely flat.

Also, your drivers seat and front passenger seat cannot be all the way back, they need to come forward some in order for the second row seats' head rests to clear and fold flat.

Start with removing the head rests. There is a handle on each one on the backside. push the handle and lift the headrest up till it comes out. You'll find a handle looking appr. 1" out of the seat, you'll see it near the door at the hind quarter of the seat. Pull the handle up and the seat will lift and swing. Swing them up to upright position. at the bottom of the backseat, back upholster you find another handle on each inner wheel cover. press them back wards and pull the seat back down.

There is a spring that pull's the handle back to lock position that might be broke or the locking mechanism might be gummed up.the spring can't be bought seperatly so check a hardware store or replace the seat track assembly.

Push down on the seat then pull the handle or both at the same time then pull up while holding the release up, it got me at first, but thats how i got it
