With the engine at full operating temp, locate the 2 heater hoses where they go into the firewall and feel them to see if they are both hot to the touch.
If you find that they are both too hot to hold, then the heat in that vehicle is controlled by a blend door that regulates heated air flow. It is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.

Where is the heater blend door located in the toyota solara

Here is the location of the blend door actuator (Diagrams Below). The actuator is above the gas pedal and can be seen when looking in that location without removing a number of trim pieces that is required to replace. It is not behind the glove box on the 99 Solara.
Here is a guide that will walk you through the procedure on how to fix it.
