Furnace runs but no air is blowing through the vents

Sounds like a major water leak somewhere.

Yes, I suspect something happened before I bought it (used). Probably some leak/flood that was cleaned promptly but nobody thought about the ducts.

Yeah that makes sense. Ouch.

A followup question. After removing the kitchen island registers I noticed there's 2 ducts underneath, tied together but only one has air coming through it. What is the second one for? Is it for warming the underbelly?

I have a 315RLTS and have had the coroplast down to repair and modify stuff. The two ducts should both be carrying heat to the register, they are both connected to the furnace. The ducts cross between a frame crossmember and the bottom of the floor that crushes them down to about 2 inches high. Possibly two ducts were run to make up for this. There is a 2 inch duct that is used to heat the underbelly laying on top of the coroplast.

Have Imagine and duct work was one of main issues I had; broken, not connected, not routed correctly to underbelly. Should have been caught at factory in their quality checks that they brag about as being so good.
