my Mazda B2600 isn't heating the cab. The fan works but I get no heat from what is blowing out of the vents. How would I fix this?

First get the vehicle to a warm operating temperature then turn it off and pop the hood.

Feel the heater cores directly at the firewall, let me know if:
one is hot and one cold or warm
both are hot
or both are cold.
