Hi anyone give me some advice on how to proceed with fault on this peugeot please. Engine running, the single cooling fan in front of radiator is running at high speed all the time.no fault codes present in engine ecu and live data shows normal coolant temp.can find 1 fan relay but autodata wiring diagram shows 3 and looks complicated to follow.have a suspicion that it is in fail safe to protect the auto aircon that is not working.i cant access the aircon ecu or in fact airbag or auto seat ecus.abs and engine ecus are readily accessible.the aircon clutch is not pulling in and we have checked and topped up the system pressures.the car has some intermittent problems with the indicators and auto lighting my long shot is could this have a bsi fault or can bus fault that is affecting all these related faults if so where do you start testing or am i over complicating matters when i see "unable to communicate ". thanks in anticipation paul
