That bit of metal, I think, takes the heat of the heatsink to a thermistor on the printed side of the board.
When it’s too hot, the thermistor switches the motor off.
If the thermistor is loose, it’s like high resistance, and the motor won’t spin.

Sorry to jump on this thread, but we've got the same problem a 2001 Xsara HDI aircon heater not working at all. Have changed the transistor board unit and tested the motor assembly out and it runs off a battery and in the car when you short the yellow and orange wires. Connected up properly it doesn't run at all. all fuses are ok too. I did buy the green resistor and thermo link thing but cannot find where that might go in the heater ducts. the heate drear window works too which means the ignition switch is probably ok I gather ? Do the heater rheostat controls burn out ? If so,how do you get at it ? any suggestions or ideas would be very welcome thanks !
