I have no idea.
What happens when you run the defroster ? are the driver side window aimed vents blowing ?

Same no driver action in AUTO and Manual mode ?



Maybe disconnect battery for a while.

or

Run the heat on hot maximum blower setting,

And chk the cabin filter it it's clogged maybe the system shuts down partially.
