Fan is blowing but no heat is coming out

check the heater core and change the thermostat

if the car is over heating then the heater core is bad if not then it is definitely the thermostat

if it still continues then check the heat control panel

No heat. blows but not hot

same problem here. so far ive determined that the car has the right amount of coolant, and the engine is running at the right temp the fans turn on and off and the thermostat seems to work correctly. someone advised the problem was the heater shut off motor but I dont know where it is or how to check it yet, anyone? also the car did make some noise from the blower motor so maybe the heater core is blocked with leaves or someting, ill check all before i bring it to the dealer.

I also ran into this problem on my 2002 Galant. I've found that the heater control value tends to get stuck on these vehicles, especially when the heat has not been used all summer. It will make a clicking noise from behind the dash when it fails. This is a common problem. See
for more information.

Heater system not working/heater value system /switches control working, but no heat, put theorstat in and no heat still/

Hello there :
What you are going to have to do is either check out the heater core by a shop or you can do it your self.
Check to see if all of the wires are connected to the heater motor and see if the heater motor is working if not replace it if it is working than i would then look into having the heater core replaced OK?

The heater blows cold air and the anitfreeze is leakig

the clamp is definitely not tight... tighten it first and see if there is a change in heat also refill what you lost in antifreeze also see it the hose itself is not leaking if so replace both to be sure and possible flush the heater core while your at that point .

Heater wont get hot

Make sure the temp door is moving when you change the temp.then change the thermostat out with a new one.Bleed the system of all the air in the cooling system.If still,no heat,remove the heater hoses from the heater core,and flush the heater core out with a water hose.In one pipe,it will flush out the other pipe of the heater core.
