Laguna thermal fuse - follow up.....
My son had this problem on his 'phase 1' about 4 months ago and 'my' solution to it was for all practical purposes identical - (got an RS account which helps when getting awkward bits like thermal fuses!).
My point is however, that thermal fuses are there for a reason, i.e protection when things get too hot - which in this system probably means poor or diminished airflow, ( given the resistor pack is 'naked' and housed directly in the main blower pipe to keep it cool).
While you've got the glove-box out it only takes an extra 10 minutes to uncouple the blower motor ( up against near-side panel) and check inside the housing and entry / exit pipe(s) for debris.....of which there was quite a bit on my son's Laguna.......mainly dry leaves.
This seems to be so common that maybe this fault is worthy of a few jpgs to point people in the right direction.
Perhaps we could set up a source for 110'c thermal fuses !!
