Any tips on how to clear the blockage before I start?
It depends on how long you let it click for, if you let it clicking until it stopped, then you will most likely need to take that fan off, and just the front of the extruder case (nothing falls apart, its pretty easy) and get the gunk out, because most likely its ground to a powder in there and clogged the gear.

If it only clicked for a little bit and you stopped it, then you might be able to do a preheat purge, ie set your preheat to like 245c and see if that can get the main gunk out, then try feeding filament ontop of that to push it through.
