I have had this problem, and I am having it again. The problem is if a little trash gets under the bar in the floor, it will keep the mechanism from locking completely. I had tried everything. The only solution so far is the rock back and forth. Real pain. I am trying to find a secret release.

I solved the problem by spraying WD40 into the front side of the seat support that was sticking. This support has a rubber closure to protect the mechanics of the seat. After spraying a generous amount of WD40, I waited about 5 minutes and tried the lever to fold the seat. It worked and still does.

you have to pull the part you sit on up and forward (to front of truck) then the backs will just fold down sams as trail blazer

Tips for a great answer:
F1.8 10 Electronic Automatic Temperature Control (EATC) module (19980), Exterior
rear view mirror, left, Exterior rear view mirror, right
F1.5 7.5 Powertrain Control Module (PCM) (12A650), Deactivator switch, Third row
folding seat relay, left, Third row folding seat relay, right, Power lift gate
module, Brake pedal position switch (13480), Sunload sensor (19E663),
Clock (15000), Function selector switch assembly, front, Electronic Automatic
Temperature Control (EATC) module (19980). Don't think you have a fuse problem ! More then likely the HVAC control module is bad , they do go bad
