Not sure, but it cud be very old and choked AC filter also known as pollen filter. Get that check or changed and see. I am quite doubtful on that.

If you smelling carbon smell then you might have exhaust leak near exhaust manifold and CO (carbon monoxide) is coming inside car cabin. Which is very risky for health if you dont fix it it time.

Check the first option of AC filter first and then doubt second one.
