The fan under and behind the glove box is bad. I just bought one on eBay for $75. They are over 300 at the dealer.

I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend
gas leak or wrong wiring
could be low on coolant
Temp blend door malfunction.

It doesn't really blow it out it just warms the cold air.
does the fan work? is the system charged with the refrigerant?
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
If it does blow just not cold air you should see if it needs to be recharged
