ok - so I think I understand how this is supposed to work...though I don't know I fully trust the Renault wiring details - or the diagram of where the relays are..nor do I trust that when the fans were replaced before my ownership that someone got creative with the wiring...so a perfect storm...
I made a diagram based on what the wiring book seems to be telling me...but for the reasons above, this may not be reality or correct:

Case1: AC switch is on both fans run at ~50% (in series)
Case2: Rad is at 92C both fans run at 50% (in series) (switches off at 82C
Case3: Rad is at 95C both fans run at 100% (in parallel) (switches off at 80C)
Does this sound like what was intended ?
what confuses me is how on earth just the one fan works with the AC button pressed - in principle that should not happen if one fan does not work ...as they appear to be wired in series.
I think I just need to go and test...I think I'll put some breakout wires in the relay panel to work out what's what...in the worst case I could probably manually wire up the other fan to the relay panel.
I've no idea what the thermal cutouts are either...maybe that 298 item is broken
If anyone has any bright ideas pls let me know !!
