Okies... so ive unplugged the injector electrical connectors and number 3 was looking dirtier than the rest so i sprayed with wd40 let dry out and then replaced the connector....
turned key to MAR, plugged in my Geniscan handheld thingy... (would have gone to option 2 fiat/alfa scan + laptop, next stage) and cleared the fault.
Started engine... all peachy... no error and smooth revs etc... fixed for now i reckon.
SO... then while out braving the cold, i got under the passenger footwell and removed the interior cover (2 screws) and had a poke about... tis quite interesting under there, so i uplugged a few connector thingys here and there and had a good feel around to see if it had dried out at all... seemed dry enough, so why are my blowers not working... ?
So anyway i plugged it all back together, replaced cover and turned on the heater for curiosity sake and hey presto... full blowing heaters!... magic hands today i think... Take to dealer??? pifffftttt... unplug and re-plug EVERYTHING!
Happy Christmas everyone lol!
