Anyone know why the fan would stay on. It’s the heater fan on Scania , 4 speeds. It seems to be on speed 2 when off, can turn to 1 sounds same, turn to 2 sounds same, turn to 3 it’s faster, and 4 it’s faster .

Ease off the mushrooms dude…
If the A/C switch is on then the fan will run all the time.
How old is the truck, mine did it when the weather was hot and the radiator couldn’t cope with cooling so a little sensor near the heater motor kicks in the heater matrix helps with cooling, check your viscous fan is working and your radiator isn’t blocked mine needed both.
