Hi I have 2009 DB9 Volante

My Driver side set will only move up and down. It moves only like a cm front and backwards. Back rest will move back and forth.
Passenger side seat works fine.

I have tried recalibrating seat by disconnecting battery, connecting positive and negative cable together for like 30 min
reconnect battery
Move set forward--> upward first rear half and then front half and then back rest all the way forward..

Dealer tired to calibrate and he could not so they said lets just replace seat module.

I wonder if I can swap module form passenger side to driver side and see if problem persist.
I was wondering if something is blocking the movement of the seat and wanted to remove it but i am not able to reach rear anchoring bolts as seat is not moving forward.

Any ideas, how to confirm if seat module is bad?

Thanks.
