Front Seat removal problem on a 2006 Pontiac Gran Prix. I have tried to run the seat all the way back but the front seat Bolt goes down into the floor but when you look UNDER the car there is No NUT there to loosen. I thought that I might have to take the seat loose from the tracks and then try to figure out how to get the tracks out? I haven't run into this kind of a problem before. Maybe I'm just not looking good enough? I haven't even tried to get to the front seat BACK Bolts yet as I got hung up on the front bolts. It may be something as simple as an inside bolt a little further back and that front thing that LOOKS like a bolt may be just an alignment pin? Any other suggestions? Thanks, Warren

There are only 4 screws and bolts to hold down the seat. Only the screws will come loose.

The three usual ways to remove lower portion of seat (depending on make of vehicle) are -
1. If possible move front seats all the way forward and get in back so you can use knee to push in hard (towards back of car) on lower section while pulling front edge up. Seat is hooked in tab on floor of car. You have to do this on both sides.
2. At spot where carpet goes under lip of lower cushion look for small tabs. You pull the tab and pull up on front of seat. Again on both sides.
3. At rear edge of lower cushion press down (usually near those tabs for car seat) and look for bolt that holds back of seat in. You have to crush cushion down and use a light but you will see a bolt on each side that must be taken out. Bolt is going through a metal hoop that is part of seat frame.

two bolts hold the front of the seat down and five bolt hold the rear.
the 2 front bolt require a E10 socket.

Drop the headliner & put drain hose back on

You can replace it as long as the one you are replacing is the same set-up. If you have a manual adjusting seat and replace it with a power seat it will fit but you wont have the hook ups for it. Also make sure if it is a bucket seat (single person) you dont replace it with a bench (3 persons fit in front) seat or you will run into problems with the center console and shifter. vice versa may bolt up but there will be a gap between the 2 front seats

In your situation I think your best bet is going to be taking out the back seat. Luckily this is very easy and will allow you easy access to your truck and jumper cables. Okay in order to remove the back seat you will have to have a socket set. There should be 2 bolts holding the bottom of the seat down and you can find them on the floor on the front part of the rear seat. One bolt on the driver side and one bolt on the passenger side. After you get those bolts out you should be able to remove the bottom section of the seat. If you can not look for two more bolts on the back part of the seat. You will have to look between the back of the seat and the bottom part. After you take those two bolts out both parts of the seat should be free and you can remove them. I hope this helps.

Move the seat all the way back and the front bolts will be accessible.

You will need to crawl under the vehicle. The bolts holding them down are located there. You may need two people. One to hold the bolt secure insde the car and one to turn the bolt from underneith. There maybe as many as 6 bolts per seat. I am assuming these are bucket style seats. Tell me how it turns out, Raz

On W-Body vehicles, the front seats are secured to the floorpan by two front hook attachments and two rear bolts installed to nuts welded to the floorpan.
The manually operated two-way front adjusters provides only fore and aft movement of the seat. When the seat adjuster handle located on the front seat is pulled up, the seat adjusters unlock, permitting travel of the seat. When the seat is in the desired position and the seat adjuster handle is released, the seat locks in place.
A power operated six-way seat adjuster is available. The adjusters are activated by three 12 volt, reversible, permanent magnet motors with a built-in circuit breaker. The motors are energized by a switch bolted on the seat side panel.
The three motors drive the front seat and rear vertical actuators and a horizontal actuator. When the adjusters reach the limit of travel, torque is absorbed through the rubber mounted grommets located between the motor and the support. An overload relay is provided in the circuit and will open should excessive stall be applied.
The optional 60/40 split bench front seats have seat back head restraints on the driver's and passenger's seat back. The head restraints are designed so they cannot be removed from the seat back without first inserting a small rounded tool inside the head restraint support tube to release the locking tab. The 60/40 split bench seat is equipped with a reclining mechanism on both the driver's and passenger's side. The recliner lever is located on the outboard side of the spring cushion. When the lever is pulled upward, the spring loaded dual linear reclining unit located in the cushion frame is released, allowing the seat back to be pushed rearward or allowing the spring loaded reclining unit to bring the seat back forward.
Bucket seats are equipped with manual reclining mechanisms. An optional six-way power seat adjuster is available. Some bucket seats are equipped with inertia seat back locks. This system allows the seat back to fold forward without requiring the occupant to release a locking lever or access to the rear seat area. During a sudden stop or deceleration, or if the front of the vehicle is nose down, the inertia system of the seat back lock will engage, holding the seat back in its rest position. A release lever is provided to allow manual release of the seat back lock when the vehicle is in the nose down position. The release lever is located at the lower rear outboard corner of the seat back.
Some W-Body vehicles (notably Pontiac coupes) have passenger front seats equipped with an E-Z Entry device. This is actuated, in an unoccupied seat, by completely folding the seat back forward disengaging the adjuster, and sliding the front seat forward to gain access to the rear seat area. To return the seat to its normal position, return the seat back to its rest position, and slide the entire seat rearward, engaging the adjuster.
W-Body rear seats are available in several styles including a rear seat with an integral child restraint device.
