Well, you are supposed to be able to pull on two straps coming through the seat belt holes in the seat and the seat bottom fold forward into the floor. Then you just pull on one of the buttons on the top of the seat and then lay the seat back forward. Unfortunately, mine seems to be broken and the bottom straps don't seem to unlatch and allow the seat to tip forward. Big favor, if you get your to work and figure out that there is some lock mechanism that is stuck on mine, then let me know.
I also had this problem, what i had to do is, pull both buttons at the top of the back seat then while standing as best you can in front of both pull straps pull them at the same time. Its kinda odd, but you have to pull them with equal force at the same time then they will unlock and come down. the only way I've been able to do this is while standing in the vehicle.
If it is anything like my husbands vehicle you have to take the head rests off to lay it down flat

You can get a diagram for the driver door lock mechanism for a 2001 Isuzu Rodeo at various auto part stores. You can also check in the owner's manual.

See www.isuzufaq.com entry 41. "How do I reprogram my keyless entry fob?" The first procedure (turn key 3x, close & open door 2x, turn key 5x, close & open door) worked for my 2002 Rodeo.
Look under the drives side door. It is a small canistor protected by a heat shield. It is about the size of a soup can.
Because the outside handle has lost it's connection with the locking mechanism.
Definitely sounds like an electrical problem. First check the fuse that controls the window circuit to be sure it isn't blown out. If it's okay, then the switch could be faulty or the wiring leading from the switch to the back window motor could be broken or shorted out somwhere between the drivers position and the back of the vehicle.
There is a plastic cover inside the rear door jamb along side the tailight assembly. This cover snaps off and back on but take care not to break it as it does take some effort to remove.
