Poor heat

My heat seems to work but only when I'm moving, even when I am moving the heat is barely there. Also there seems to be no difference between hi and lo, it blows the same no matter what. Is my problem the blower motor?

pull the blower motor out and check it on the workbench and look for leaves stuck inside there.

I would bet it's a bad blower motor. You should also read through some of THESE threads from the FAQ and heater stuff, lots of good info in there.
