Heater problem
1999 Peugeot Expert Two Wheel Drive Manual

Hi can you help, the heating in my peugeot expert has decided to die, it worked on and off and flashing the main beams made it kick in very strange, but now the fan wont start at all, ive checked fuses in the main fuse box in engine bay and have removed front panel where heating controls are and there is no power to any of this when checking the connections feeding the removable circuit board is there possibly any fuses i havent found or a relay that turns this on and off with the ignition switch? Any clues would be great

Many Thanks Antony
