Rear seat won't come back up

You have to remove the seat bottom cushion first by pressing your knees against the seat and lifting up on it to disengage it from the frame brackets then there are bolts where the seat belt is that hold the top part once taken out you must lift upwards to disengage the top of the seat from those brackets and your in but you should check your fuses for the power trunk or run 12volts to the switch unless the lock is broken inside then doing what your about to is the best choice

if is like mine 2003 open your tailgate and the hole is on your right and the stuff to lowerd is under back seat also read carefully the way to lowerd because there is a special way to do it !
i hope having help you !!
stephane

it is rusted to the latch. soak the latch under the seat with wd-40 and wait a day. then try again. if it doesn't work then use a screw driver to pry open the seized latch.

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.

If your top is electric then you will need to release the front cowl motors at the center point of the trim in front of the rear view mirror(small access plug needs to be removed and allen key inserted to drive unit.) You also need to pull the release handle under the back seat bottom(driver's side) The release handle detaches the drive units for the storage lid cover and the convertible top drive. Once the motors are released, the front of the top must be lifted approximately 6 inches and the pressure against the rear of the top will relax. raise the rear bow, open the storage lid, lower the rear bow and push the front of the top up and toward the back of the car. The top should fold into the storage area. Once in, close the storage lid until it clicks.

Thank you for the inquiry.
Ok, I know this is old but to help anyone in the future...
It is really, really easy to remove the rear seat cushion.

You just push the bottom of the seat cushion in and lift up.

Keep rear seat back in upright position.
You need to unlatch the rear seat cushion at 2 points, which are at the center of each seating position. You just squish the seat cushion towards the back of the car, right at the bottom where it meets the carpet and lift up. That half of the seat will popup, then repeat for other side.

It takes maybe 5 seconds to do.

You won't beleive how easy it is 'till you try it.
This is how many, many cars mount there rear seat cushions.

Rear bucket seat won't lift to the seating position. We folded the seat down and the seat is now locked in the down position.

most likely the top pistons start to leak and the motor can create enough pressure to actually lift the top back to go in the storage area... i would let the tonuea cover lift open then get out the car and look around to see for fluid residue.. if not and there are no leaks.. possible the seals in the pump it self has gone out.. and the motor is still trying to pump... the pump and motor is located behind the rear seat under the small plastic panel/.
