Hi: Is the engine warming to normal operating temp? Is the coolant level full? If you feel the heater core hoses when the engine is hot and the heater is on, are they both warm?

Let me know.

What does the temp gauge read (the one that looks like a thermometer [most times])?

Was the heater core flushed? I flushed the heater core on my Blazer and the heater is hotter than ever. Take both hoses off that are coming from the radiator and hitting the fire wall. Get your water hose and put it on one and then the other. Your going to get wet but it will work. If that is not the case then check the thermostat. Thanks

Hi: If both hoses are hot and the engine runs at a normal operating temp (around 200 degrees) there must be a problem with the blend door not opening to allow heat to enter the cab. Near the heater core is where you'll find the item. It's located in the HVAC duct work and may be stuck.

Check for that and let me know what you find. NOTE: The heater core is aprox behind the glove box.

Let me know if this helps.
