seriously make sure the A/C light is not on, If not then it may be time to get the heater core looked at. Check and see if the A/c works. That way we know if it is a blower / blender valve problem or if it is something else

There is a self diagnostic for the HVAC in the Helms manual.
How to retrieve an HVAC DTC.
1.) Set the mode control dial to vent. (far left)
2.) Turn the ignition on.
3.) Within 5 seconds after turning the ignition switch on, press the recirculation control switch the required number of times depending on the recirculation indicator status:
If the indicator is ON, press the recirculation control switch 5 times.
If the indicator is OFF, press the recirculation control switch 6 times.
The recirculation indicator will come on for 2 seconds, Then blink the Diagnostic Trouble Code to indicate a faulty component. If no DTC's are found, the indicator will not blink after the initial 2 second light.
HVAC DTC's
HVAC DTC 1.) A problem with the air mix control motor circuit.
HVAC DTC 2.) A problem in the mode control motor circuit.
HVAC DTC 3.) A problem in the blower motor circuit.
HVAC DTC 4.) A problem in the evaporator temperature sensor circuit.
*in case of multiple problems, the recirculation indicator will indicate only the DTC with the least number of blinks.
*in case of intermittent failure, the heater control panel will store the DTC until the ignition is turned off.

did you check the heater control valve?
on th passenger side of the engine compartment, the heater hoses that runs into the dash for the heater core. there is a valve that closes when the temp knob is turned to "cold". it opens and allows hot coolant to flow through the heater core when the knob is turned to "hot".
