The heater in my neon doesn't blow out hot air. It blows air out fine but, it isn't hot or even warm. If it is on the lowest blow setting it seems to feel slightly warm if I put my hand right against the vent but, not enough to heat the car. If it is blowing any more forcefully it does not feel warm at all.

Can you tell me what needs to be done to fix this issue? It's been like this for 3 or 4 years and I am determined to get it working this time even if that means doing it myself. I have probably spent at least $1000 at service shop over the years trying to get this fixed. Thanks

With the engine at full operating temp, locate the 2 heater hoses where they go into the firewall and feel them to see if they are both hot to the touch. If they are both hot, the heat in that vehicle is controlled by a blend door that regulates heated air flow. It is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
