Looks like things have gotten hot here before


This is what happens when you don't got a cabin filter (I have fitted one a few weeks earlier)

I cleaned the fan, oiled the bearings and put it back together. It does start but rpms are not consistent on max speed. I will need to remove it again and test it on my 12V bench supply, if it runs steadily there when the wiring is the issue, perhaps brad ground, or perhaps further "upstream" at the MCC unit.
