99 406HDi GLX - powered seats with no power

Hi folks,

I posted a question about a week ago which ties in to this current problem.

Originally my ignition switch/barrel disintegrated and jammed. It took a
few days for the new lock kit to arrive and get fitted. However, when I got
the car back the front powered seats are dead. There is no movement
whatsoever but the fuses seem to be intact.

Does anyone have any idea if there are any other fuses or dodgy places worth
checking that might cause this problem? The mechanic is checking out other
possible causes over the weekend (not a Pug main dealer).

The thing that is concerning me slightly is the fact that the seats are
factory fitted leather and not standard - although I am fairly sure a 99 GLX
will have powered seats. But could this be an issue?

Thanks in advance (yet again) for your help.
