Question about 2002 Ford Explorer
Sounds like something in the fan. If you turn the fan speed up, does the knocking speed increase? If so, pull the fan, maybe soemthing came loose or stick in it.
If speed does not change, you may have an air direction door issue. You just need to investigate. Surgery to air boxes is fragile and difficult, you may want to have a shop do this for you...
