I was removing the rear seat in a Kia Sedona. However, the front clamps (of the seat) got attached to the rear bars and now I cannot get the seat out. Any advice? Thank you.

are you referring to the drain plug? if so, it is located on the passenger side bottom facing the front bumper. see attached diagram under radiator removal. http://www.kia-forums.com/attachments/kia-carnival-sedona/9678d1319024147-removing-radiator-kia-sedona-2005-remove-radiator.jpg

Remove the rear seat, remove the access cover and disconnect the electrical connector on the fuel pump. Start the vehicle and let it run until it stalls. Disconnect the neg. battery cable. After the repairs are done reconnect the electrical connector and attach the neg. cable.

Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

Ditto for me. My son accidently latched one of the rear latches but none of the others. We could not get it off. We found this answer and tried it and it worked. I lifted on the rear of the seat while he folded the back of the seat down. It released when we did this. Whew

The rear seat removal is covered in the owner's manual on page 3-25.

yes, usual you will find coins or something lodged in the treaded bar on the seat motor, if not water damage can corrode the bar, check the bar as it goes in and out. ( rate me )

move seat completely back.take off head restraint,tip backrest forward flat to seat, then, grab the pull cord and pull backward so that seat tips forward then grab bars on front of underseat and squeeze together and lift.be careful these seats ARE HEAVY.

clean all debris and lubricate with silicone lubricant, push seat in direction of full contact with back of hook, try to operate lever

You should be able to... There should be a bar or a ******** the back of the seat that you can just pull...

Got it, with the help and eyes of my wife. The rear latch releases as the seat back is lowered. This release is ALMOST seat back down (about 3 inches above the seat bottom). As the seat back lowers, apply constant lift on the rear latch, and it will release as the seat back lowers. Hard-won knowledge - I think I invented some bad words in the process.
