Check the water pump.. Check the pullys

Your thermostat may be stuck open and your coolant isn't getting hot to warm the cab.Here's a link on how to replace,very easy to do.Don't let your pets near spilt coolant,will kill them.

There is probably some kind of damper that opens and closes under the dash that allows the air from the blower to be blow across the heater core under the dash. Sometimes these are controlled electronically or by vacuum tubes. Look underneath the dash and look for small vacuum hoses that might be dangling loose or possible little wire cables that might have come off the sides.
Possibly check Haynes Manuals (www.haynes.com) to learn how to change a Heater Control Valve.

just follow the top radiator hose to where it attaches to the engine. There should be a housing held to the engine by 3 bolts. On the v6 it's much easier to access if you remove the battery and the battery shelf before you start.

both hoses is hot signifies thatcoolant circulation is just fine check the blend door actuator it might be stuck.pan the heater temp controller from hot to cold do you feel any change in temp of the air from the blower?if you dont feel any change check the blend door actuator

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.

try to back flush the heater core. and if that dont work check the blend door it see if it is working.

check thermostat and coolant level

This may be a solution:
I had a similar problem at the beginning of this winter.
My heater was blowing cold air.

My solution:
Heater Temperature control cable, about $10 from dealer
Install, about $70, at my local Firestone
