hi, you say there is no HEAT coming out when blower is on .. is air being blown out of the vents? .. if YES, cold air, then the problem may be an air lock/ a valve stuck closed/ or low coolant .. could be a problem with the air conditioning controls. If NO AIR blowing out of the vents and you can hear the fan blowing then investigate, controls to open and close vents, or possibly disconnected ducting .. if the car has been stood a long time it could be sticking vent/door/flap .. search internet for diagram of heating system for more information.
okay temp is not hot enough check thermostat temp rating is it 195 degree etc. are you in a cold climate state? Maybe you need to get a thermostat of a hotter degree[four seasons 195 degree should do it]. If this is what you have (195 deg. thermo) then it might be stuck open not allowing the heat to build up. Another possibility is air in the radiator system, bleed system.
This too might be of help the blend door, which is operated by the HOT to COLD lever on your climate control panel, might not be moving all the way closed to stop the cold air from coming in the mix area with the heat. Move the lever back and fourth to feel any change in heat with your hand. Put the defroster on fan on high and put one hand near the defroster vent thee other hand moving the temperature selector. Do you have some sort of heat and you can feel the difference from hot and cold, then my recommendation is to check thermo degree rating, if ok then try to flush radiator, and if that does not work --replace Heater Core. Thank you for allowing me to help you if you need me just write,Lee
check the coolant level & condition of antifreeze make sure it is not dirty/rusty/muddy if thats ok try a new thermostat & radiator cap if the antifreeze is muddy you may have to blow out the heater core
