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.
