2006 Vanquish S - upgraded years ago to DRL's at AM Dealer in U.S. before car was exported to Canada. Now- Low Beams do not work when vehicle started like they have for years. High Beams work. I need to check the DRL Module - but can't find it. Does anyone know where it might be located on the car?

 

That feature is integrated into the Body Processor Module, not a standard alone system.
