You didnt say if it was electronic temp control or not. If you have electronic control, the control unit could have gone bad. When you change the temp from warm to cold can you tell any difference at all? There is also what is called a "blend door" that either gives you warm or cold air. This is controlled by a motor. I have seen the motors go bad, I have also seen the tab that the motor attaches to break off.

One more thing. Do you hear any clicking noises when you change from warm to cold air. If yes you need the motor.

 

how can I tell if it is electric control? before I flushed it out it had no heat and afterwards very little. not even enough to defrost windshield.

 

Is coolant level up? Have you checked to make sure after running car and shutting it off, and after it cools down that coolant level is right under the radiator cap (if your vehicle has one.)?

Have you felt the heater hoses to see if one is hot and the other is cold while the blower motor is off, or if both are cool? Or if the one is hot and the other turns cool after you turn on the blower? Or if they are both still hot after you turn on the blower? Each of these signifies a certain possible problem.

Is your water temp gauge in the normal operating range it has always been in, or is it even higher than normal?

 

normal operating range

 

Please check the temps of the heater hoses as suggested (if you can get to them), by physically feeling them, each, as that will provide needed info.
