the fact that the car runs well indicates that it is not the ECM ( brain to mechanics who have little idea)
take the vehicle to an accredited service center who has experience on your make of vehicle and have the fault codes read and then fix the faults reported

Before you remove any airbag you must disconnect the battery and wait for at least 20 mins for any power going to the bag to discharge fully.If you don't,upon removing the connectors on the air you run a very high risk of setting it off.

The motors responsible for moving the seats are not being properly powered. The issue could be due to blown fuse, bad relay, bad connections, bad switches, ad infinitum. In short, any part in between the power source (battery) and the motor is suspect.

Get a hold of the wiring schematic for your car, study it, and get to work.

The Lighting Control Module can only be replaced by the dealer or by someone who has the factory scan tool. The new module has a blank memory in it. The tech needs to upload the memory from the old module, then donload it into the new module.
Sorry to burst your bubble.

The lcm is mounted in the same location in all crown vics. It's under the dash, above the gas pedal in between the climate controls and steering column. If you're having trouble locating it, engage the hazard flashers and listen to where the source of the clicking sound is coming from. You can also place your keys in the ignition and open the drivers door and track down the module by listening to where the warning buzzer tone is coming from.
