rear window relay location

Hi, i have a 2006 L322 vogue. having a bit of an issue with the drivers rear window, all the rest are working fine. I've just changed the window reg and motor as the motor was stuck as it's never used. Put direct feed onto motor and it wasn't moving. Now fitted new one, checked and working. Now there is now power. I'm putting this down to strain from the old motor. Just done a diagnostic and it's coming up with driver rear door up relay short to battery and driver rear short to ground up relay. Does anyone know where this relay is located please.
TIA

I take it you have checked the fuses.

I think you will find the relays are inside the BCU, but not 100% maybe somebody else will confirm.
