Does anyone know if there is a separate unit/module that controls the seat memory buttons. I can hear a relay clicking noise when I push one of the memory buttons but no movement on the seat.

Yes there is a separate ECU for the driver's seat and the mirrors and another for the passenger's seat. I am not sure of the location.

The first few pages should give you idea of the general location of the ECUs but I am not sure where it means, under the dash or in the transmission tunnel??

I do not have power seats I can't help much here. Try to use that diagram and trace power back until you find the issue. Maybe someone with a newer model can chime in to help you out.

The units are literally under your feet. To fit the stuff, Jaguar put a sheet metal hump right in front of the seat and just carpeted it. There are two little metal screws in the front, and it just slides out.
