2003 mitsubishi galant es 4cylheater blowing nothing but cold air
I turned my hot/cold switch the other day to the cold setting because it was warm.... and then when i turned it back, its blowing nothing but regular air.... not air conditioned air because it the cold air conditioner setting was not pushed in. Is there something specific that would be the problem? how much would that cost to fix?

that happened to me the heater core went out ive read alot of different things about 03 galants most of them have the same problem it started with a grinding noise turning the temp contol, its actually the heater control motor value it causes the heater core to go out
Does the air blows through the dash board vents. Does the selector is functional, that means you can force the air stream through wind shield, or vents or down to the legs. If these things are OKthen check CONTROL PANEL.
Remove the trim plate surrounding the center instrument panel. Detach the electrical connectors and remove the control panel.
You don't say if the fan is working. If not, check the fuse. If the fuse is okay, check the switch and fan motor to be certain they are okay. If the fan is working, and still no heat (blows cold air), there is something blocking hot water from getting to the heater core. I hope this gives you some help to isolate where your problem is.
try driving around for almost 4 months and the damn thing wont blow cold. try spending thousands of dollars and it still being broken. and trying driving in florida in upwards 115 degrees with no cold ac everyday. you only have to wait 30 minutes? count yourself lucky!
I had the exact same problem, yes it was the heater control valve, the repair was 285.00. The tech that replaced it told me it is a common problem for the Galant. He said that if you keep your temp selector on either all hot or all cold that it keeps constant pressure on the plastic gear teeth in the valve. As they break off one by one you begin to hear that clicking noise as the dont catch. When you finally break off the last one it stops working.
According to him if you always leave the dial at least one notch from fully hot or fully cold you will not experience a failure of the switch
There ia an actuator that controls the flap to change from hot to cold. You have to pull the bottom part of the dash and the whole blower motor housing. The part you are looking for is located just behind the radio and has an arm that goes into the heater core line. That is the piece you need. Its around $165 dollars and a dealer only part. And hope you have someone that can do it because mitsubishi charges over $500 in labor.
sounds like the fan controller switch in the panel has gone nutty. I would take the car to the dealer and let them diagnose the issue, they are best when it comes to knowing your car the most and in diagnosing problems with them better than just a regular joe blow shop that works on everything and doesn't specialize in any particular issue.
