Do you currently have a stock fan? If so, clutch or solid drive? Even if clutch, clutch might be seized up.

Possible the 195 Tstat was defective. QC isn't what it used to be.

Is it possible your heater core is mostly plugged? Or the heater box is full of grass, mouse nests, etc.?

The cardboard idea is cheap and easy to try.
