L322 elictric window and heater fault.

Hi Guys, i acquired a 2003 TD6 HSE yesterday which has not been looked after at all so i thought i would spend the next few weeks tidying it up and then use it instead of my 4.4 V8 Autobiography. Most things seem to work fine except the electric windows which do not go up or down using any of the switches and the fuse is not blown. secondly the heater, A/C panal lights up as normal but the fan does not blow. Does anybody know of any common faults with these two items. Thanks for any help.

Get the ecu tested for the faults
