What is your question?
So for like a week every time I turned on the heat or the air my car would make this loud noise and then it just stopped and now I have no heat or air
How long has your 2008 Nissan Sentra had this problem?
A week

Sounds like maybe your blower motor may have been making noise and now is not working. This could be from a blower motor failure or some kind of debris being present. Physical inspection and further testing is required.
