2003 GALANT ES. HOT/COLD CONTROL WHEN PLACED ON FULL COLD MAKES CLICKING NOISE IN DASH. CAN ADJUST TO SLIGHTLY WARMER POSITION AND CLICKING STOPS. A/C & HEATER BOTH WORK FINE. IS THIS SOMETHING THAT CAN BE EASILY REPLACED?

I had the exact same problem, and 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

As for is it easily fixed.....no, the heater control valve needs to be replaced. I looked into doing it myself but thought better of it. Its buried deep in the dash and most of the passenger side must be removed and I still couldn't figure out how to get it out. I think it ended up costing me about 300 dollars to get it fixed by the shop.

problem one the blower positions first it could be the blower resistor or possibly the switch second problem no cool air there is a heater shut off valve under the dash on the right side of the radio if you change the temp control from cold to hot and hot to cold and hear a clicking ,grinding noise this valve is bad and not shutting off the hot air to the system making your a/c feel warmer , or a/c system has a leak somwhere and will have to be recharged and traced to repair it

I'm assuming you mean the door under the dash that controls your heat. I had the exact same problem, yes it was the heater control valve, the repair was 285.00 approx 3 years ago. 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. I have followed his advise and have had no further problems.

If it was making a clicking noise before it stopped giving heat here is the solution,

If not I would replace the thermostat.

Be gentle with my rating. I am a long ways away. It sounds like a fan belt. You should pop the hood next time and see how it sounds when you have the squeeling going on. Fan belts will squeel until the get warmed up and then stop because the heat makes them grab the way they are ment too. Let me know, Raz

Same problem I had for over a year...A mechanic might try to tell you it is simply the heater core (don't fall for it). There is a control under the dash that operates the temperature gauge. Basically that control is gone and must be replaced before you do have a heater core problem (which you will know, usually once your car overheats or you smell antifreeze). I know money is tough but i think price ranges on this to be done as more manual labor is required than replacing the actual part itself. You are looking at roughly $300.00.

If the clicking noise is from the dash its the heater control valve and see below

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

Heres the answer for the clicking sound
