$400 to $600 depending if it has ac or not.

Heater core changed three years ago,I changed Thermostat Heater still blows cool air.
A blockage in the heater core is the most likely cause. This is a difficult and expensive repair.
Probably around $500 or more if you have AC.
it should be on the top of the heater core box in the engine compartment, it will have a wires running to it
With proper tools and knowledge, 4 hours, 5 hours if it has ac.
If coolant is leaking inside your cabin, you have a leak in the heater core. The only repair is to replace the heater core. Most auto parts stores sell them.
Disconnect the inlet and outlet hoses to the heater and couple them together Or, if the hoses are the same size, remove one completely, and disconnect the other from the heater core, then connect it to the other engine outlet (or inlet, as the case may be).
The most likely cause is that your air mix door has malfunctioned, and will not change from ac to heat, but it is possible that your heater core has become blocked, or that there is a water valve in the line that has become stuck.
i have a 93 s10 blazer and had to replace the heater core recently, it is a pain, and it helps to have another person there to give you a hand, you have to take the entire dash out, remove the heater core cover, undo the brackets and undo the hoses from the heater core, the worst part is removing the dash and remembering where all the wires go if you do this job yourself i sugest taking pictures as you go along
You need to remove instrument cluster. And the whole dash to access heater box. The heater box case has to be slpit in half to access heater core. A very timely and frustrating job. Take to a professional is what I recommend.
$400 to $500 or more if the vehicle has AC, would be my guess.
A replacement heater core would cost aprox $35.

The heater core comes out from the inside. If you have air it is a little harder. Remove the dash bolts it does not need to come all the way out. also remove the glove box this will help you remove the heater box which the heater core is behind pretty easy after the dash is out of the way hope this helps
