Check the thermostat again and check the heater core if its clogged-up, if not could be a problem behind the dash with air mix/blend/mode door problems, vacuum/actuators and the HVAC control module-

Apreciate it! I heard that the vortec is notorious for clogging up where the tubes that go to the heater core are coming off the block so I will be draining and checking tomorrow! Thank you again!
