I would take a complete guess at somewhere in the region of 2-300 quid for a new one, second hand no idea.

This is just a shot in the dark, it's the only thing aside from the ECU that I imagine might affect all these systems at once providing the fuses are ok. But it could be a bad earth, loose plug, corroded pins etc.

any more suggestions i popped into a local alfa specialist earler today they reckon a diagnostics check wouldnt find the fault as its raining now with no wipers its quiet an issue

managed to download wiring diagrams every thing goes through a 7.5 fuse middle row left hand fuse as you look at it)in the secondary fuse box above the main fuse box. i checked and found it was blown put in a 10amp fuse and it blew kept replacing it whilst disconnecting every system that had stopped working (went through a fair few) couldnt find the circuit at fault so i have put a 30amp in and it seems to be working as a temporary fix
