Hey all
I had this problem in 2003 Doblo elx. The control module was up next to the fan and had one screw holding it in. I wrapped a length of solder across in line with the heat sensor resistor at the top of the unit and crimped it into place with pliers. Reassemble and it works. Trust the solder to melt at similar temp to the resistor if it needs to.
Still working on the erratic earth fault that puts my sidelights and dash lights on occasionally from the heater fan switch....
Dieselberg - i am the one that knocks

That was common on the mk2 punto.
