I have a y reg Marea Weekend 1.9 JTD with A/C and climate control. The radiator fans never kick in and there is a dash warning light on permanently. The brain is claiming "fan relay fault" (checked by son with ECU reader) but I have checked the relays on the bench and they all seem OK (energise and contacts). Also linking out the relay contacts in the connector by the battery bring the fans on so it must be a signalling relay coil signal) fault.
There is no sign of a radiator thermostat so I am left wondering what to check next. I believe the fans can be forced on with a Vag type lead and FIAT ECU CHECK but I am a little confused as to how cooling fan system works. The workshop manuals I have found don't seem match my car exactly
Any help or advice would be much appreciated.
