Try pinching off one of the heater hoses going into the firewall. If this causes the temp to cool sufficiently, then you have a problem with the temperature blend door.

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.
