I have a 2 story home with one unit for the upstairs and downstairs. The heat is blowing upstairs through the ducts, but there is no heat coming through the downstairs ducts.

Make sure all dampers are open on the downstairs ducts.

Go to the sticky at the top of H&AC. Start with the start up sequence. Then check the sections for where the problem seems to be.
