Blue sensor doesn't have any control over fans - just feeds dash gauge.
Green sensor is for ECU (adjusting fuel mixture)
Brown sensor is related to air con and is linked to the double fans. With air con fans cool both rad and condenser.
Best explanation I've found on the web is here http://www.peugeotlogic.com/workshop/wsh...fanop1.htm
....oh, and I'm fairly sure air con models don't have a fan switch mounted in the radiator (the 4th picture you've shown).
