Well that was easy. Remove 2 clips, unplug the fan and wiggle it out.
Bearings were dry so I sprayed it with some liquid wrench on the back bearing, drilled a hole in plastic on the front and did the same. after that I doused both sides in oil, hook it up to my battery charger and let it run for a few minutes.
re-installing it took longer than getting it out, but she's back on the road for now.

Obviously this is just a Band-aid fix until the replacement fan arrives next week.
