you will find it is the fusible link on the resister unit,which can be found after removing the glove box,it is mounted on top of the blower casing ,it has 2 wiring plugs connected to it ,and also the blower motor leads(red/black)

Hi Justin,

I have a same problem that heater only works on max temp, once you have a solution please let me know. I was looking at replacing the heater matrix which is costly & may not be relevant to this problem.

cheers

Sounds like the ballast burnt out. When the fan runs on max the ballast isn't used. On lower settings, it's used like a resistor to slow the fan down. They get quite warm, and do burn out if used a lot. Unfortunately I don't have a clue where they are on Lagunas, on Mondeos they are behind the glovebox, and cost around £10.
