Default Ventilation "Hi" doesnt work

Hello everybody,
my ventilation works since yesterday no longer on HI, only in the steps before. When switch to HI, the Fan is off.
Does anyone know where I could look for the problem?

I don't know, I don't have your van. But you can check the upfitter manuals

It won't be too far from the blower.
