What is the thing called in between the passenger and the driver seat that you can put your arm on and open to put thins in what is the name of it

Did you check in the glove box or under the drivers seat or in the arm rest thing between driver and passenger, or on the dashboard near the drivers knee?

Yes you can, it is splined so you can put it where
ever you like

Remove the plastic cap-- then the nut

under the driver side arm rest.

I have seen both wood and bricks used to put under a seat frame. Some of the seat mounts do not give you much room for using a wrench. They give you room for a 3/8th air rachet and socket. Especially if you are a little shorter you can elevate the frame and then put wood in the cavity and then lower the seat for a temporary fix.

There are some operating parts I have no name for, but they connect the gears on each side of the seat track. So the wood blocks have to fit between these parts. I can recommend a Salvage yard called "Parts Galore" which is expanding Nationwide. Again wrenching on this stuff is hard without power tools.

Can't address swapping passenger and driver tracks. Check out small "C" clamps or conduit clamp.

One thing you can check, and that is to look under the driver and passenger front seats, there should be a few wires and connections, check that these connections are good, sometimes things like bottles etc that have been put on the floor can roll under the seat and disturb the connections or passengers in the rear can accidently kick the installation.
hope this helps

The fuel pump in your 325 is under the rear seat, passenger side. Take the seat out, then pull up the rubber grommet with the wire going through it. Leave the wire alone for now. Peel up the thin rubber insulating mat. It is pre cut by the factory and not glued down. Remove the four nuts (10mm socket) and lift the round plate. Now remove the wire by sliding the plastic plug type housing back and lift the entire plug type housing up. Now, remove the hose clamp and slide the hose back off the plastic tube. If you damage the clamp, buy a new 1/4" clamp at the auto store for .30cents. Now unscrew the steel ring holding the pump in place. Unscrew this ring by tapping the ring with a screw driver and hammer. Remember counterclockwise (off). Now put your finger in the plastic ring molded into the top of the pump and pull up with some force. It is in place with a rubber gasket. Tight, but it will come loose. Be careful not to drop any thing into the tank. On the other side (drivers side) is a float/sensor. When reinstalling, seat the rubber gasket into the hole then drop the new pump/sensor into place. Your tank is like a saddle bag so it has two float/sensors. Time: 25 minutes

most cars either have a button or are activated by the seat belt being plugged in

No you need to put r/h on passenger side and l/h on driverside because of hte housings and fitting. I hope this helps. Don,t forget to rate my answer, thanks.

Thats a whole different ballpark. The center seat consoles do not lock upright at all there is no locking device, you just lift it up and it has a small bump that the lever hops over and this keeps it from falling back down. The only thing I can think of is something could be wedged in the lever or the rotating level itself is broken and holding the seat up. You may be able to see what is holding it if you move the drivers seat as far forward as possible and watch carefully on one side while wiggling the console back and forth and then do the same on the other side. If could be the lever bent and you may be able to bent it back into plce where it should be.

Let me know what you find, in the mean time I will check the Chrysler Star Hotline to see if there was a simular problem.
