Hi Overheat problem. Cooling fan not working under normal conditions. If sensor on the block is disconnected, the fan will run. Sensor replaced, assumed working ok. Relay & fuse OK. Non AC engine. 2003. 1.9

By disconnecting the temp switch you have proved that the fan circuit works.It would appear that the position of the switch is not reaching the reqd temp for it to activate.There could be a coolant flow or air lock issue.

Is it worth checking the low speed resistor?

Mine had corroded away and I only noticed when trying to bleed, it just kept boiling over as only high speed circuit was working
