Have you checked your antifreeze level? So the heater hoses going from the engine to the firewall are hot? And you are certain that your mix valve is opening? If this is the case, you may a bad heater core. I have no experience with Toyota heater cores so I can't help on the R & R of them.

have you tried reverse flushing he cooling system/heater core? maybe there is something blocked.
