I pulled out my fan motor and found about a bushel of wheat.

That will do it. Never know what you might find in there. After all, its what, 3 bolts?

If the fan is blowing air and it's not warm, you could have a plugged heater core, or possibly the valve in the heater hose that controls the temp may be malfunctioning. I have replaced the heater core twice on my mothers 95 F-150 because the engine is rusting out and plugging the core. The freeze plugs are rusting out too, but my dad just keeps putting stop leak in it.
