So the back of the passenger seat was coming apart due to broken tabs inside. This back piece comes as one part and cost atleast $150 online and even more from dealership. Here is what it looks like and i decided to fix it instead of replacing it.

1. Move the seat all the way back and place flathead screwdriver under piece and just pull up it will pop off easily. Repeat same for other side. You will find one bolt on each side. I believe 14mm size socket will work.

3. Now reach under the seat on the floor and pull carpet piece aside. Unplug these 3 plugs from ECU, this is just a precautionary measure not to pop out any airbags in the seat while working on it. They are easy to remove, just press on tabs and pull out.

5. Lift the seat from front and remove these 3 plugs from the bottom since the cable limits the room for movement of seat. IMG_3133 by umar ali, on Flickr

This small clip doesnt comes off easy so i just pulled down on cable since it is just tied with tape to this clip and easily slide off. Then use nose pliers to take it out IMG_3135 by umar ali, on Flickr
6. Now pull the seat all the way back and push it to dashboard. IMG_3136 by umar ali, on Flickr
7. Now from rear seat you can easily work on it. Pull these rubber elastic bands at the bottom of seat holding flap. This will uncover 2 Phillips screws holding the back plastic piece. IMG_3138 by umar ali, on Flickr

These are the 2 screws need to be removed holding the back plastic piece. IMG_3143 by umar ali, on Flickr
Now just pull the Back down and out. It is held on top by clip only. IMG_3145 by umar ali, on Flickr

Since you got so far, this is the motor which controls the leaning back ofseat, if it doesnt work this motor needs to be checked. IMG_3146 by umar ali, on Flickr
This motor controls the sliding of seat back and forth IMG_3147 by umar ali, on Flickr
This motor controls the seat to grow longer at knees. IMG_3148 by umar ali, on Flickr
If you want to service the seat fan underneath. Just turn filtercounterclockwise and it comes off. Now remove 3 bolts holding it in place andwiggle off the ducts but be careful not to rip the ducts. I almost ripped myduct which trying to take it off. Unless you live in very dusty environment for longer period of time the fanstays pretty clean and need no service. IMG_3161 by umar ali, on Flickr

9. I bough cotter pins of size 1/16" x 1/2" and #10 washers fromhome depot for around $4 total. IMG_3155 by umar ali, on Flickr
10.This is the small drill i have which i used to drill holes where the tabsbroke off. IMG_3157 by umar ali, on Flickr
11. Then i put cotter pin from outside and put washer on the inside and bendcotter pin and hammered down lightly IMG_3158 by umar ali, on Flickr

Only this small part is visible on outer back side but all of them will becovered by flap except one which is too small to notice. IMG_3160 by umar ali, on Flickr
Now just put everything backwards and you have a fixed backseat flap. Note: it really sucks that i had to write this DIY twice, i almost finishedfirst time and closed tab by mistake then wrote it all over again.
