I have a 1991 pontiac bonneville le and my drivers seat doesnt work (powered.) before the whole panel and pieces frll off, its go up and down, tilt. and everything but the joystick in the middle wouldnt go forward or back. then unscrewed to look at and all fell apart. pieces pouring out. now i cant reach my pedals. help plz!

There are actually 4 bolts but in order to get them all you have to pull the tilt pins and the lower bowl.3 should have helped tho,Make sure the spring is under the lock plate and the snap ring is in the right spot.

You may need to check fuel pressure after the engine warms up and shuts off. Maybe the fuel pump gets hot and stops. Have you checked for spark after it dies?

The flasher are located in Front seating area, driver side, under dash, mounted on kick panel. Unplug the old one and plug the new one in.

sounds like the bcm (body control module)

I have a 2005 Bonneville and lost my driver seat heater. The typical problem is a broken wire or connection in the seat section of the seat. If you're lucky, it may be a simple break like mine was; under the seat.
I pulled my seat out to work on it. Here's a picture of my broken wire towards the rear:

But, that didn't fix my problem. I also had a bad module. The control module is the same for both seats, so I was able to switch the modules and get my driver seat heater working. Here's a picture of the module. The module cost at the dealer is about $80-100(?)

It is under the dashboard on the driver side. There is a small cover just above and to the left of the brake pedal that you pull down. The fuse panel is behind that cover. Open the driver door, slide the seat back as far as you can, and lay on your side so that you can get under the steering wheel.

should be drivers side under dash,,u have to take the panel down,,its near the radio on the back side of the panel ,,some times u can turn ignition on turn signal on,,lesson for flasher,,to locate it,,hope it helped

Vehicle speed sensor. In the transmission by the passenger side CV shaft.

make sure tire size is correct. if so, then there may be a faulty speedo sensor.
