I have changed my blower motor and resistor I have gotten a coolant flush my tune up is up to date but some how I don't have heat...at first it was my a/c too..like it wasn't blowing out but since I put in the blower motor I have air just no heat...please need advice
It could also be that it is the HVAC controller inside the car is not sending the signal to the blend door to move to allow air to pass by the heater core. You could replace it with one from the junkyard to see if that helped.
Check the coolant level in your radiator. It may not seem right, but the coolant actually circulates through the heater core inside the car. If you are low on coolant then the heater core gets starved as it is the least critical component. If your coolant level is fine, and you bought the car recently, then it might be that the previous owner shunted off the coolant lines, keeping the coolant from going to the heater core, potentially because the heater core was leaking and it is costly to replace a leaky heater core.
