    My 2002 Galant was purchased new back in 2002. The heater worked fine until I had the timing belt and water pump replaced when Mitsu said it it was coming up time to do this. Long story short, my heater worked fine until I had these procedures done. It now blows cool-cold air when the heater is on, and makes a similar muffled noise when it blows, like its struggling to florce air out. The car itself vibrates/ ticks and rattIes sometimes until it is warmed up and even after that. I have spent $$$ getiing this done along with brake work that I have had to do many times since I've had this car. One mechanic from Raffield pulled it up from the computer and sai there was a known problem with the brakes on this model, but of course Mitsu denies this claim. I asked the questing if they could have disconnected something or not properly reconnected something when the maintainance was done but they insist the answer is no. This car is sleek and very nice looking, but if I had the chance to do it again, No way would I chunk out the amount of money in car notes/ and repairs that I have over the last several years, especially with such low miles on it. ( It was so over priced for the trouble!)

    update... regarding heater, brakes, and noise sine replacing timing, water pump! I failed to mention, my 2002 galant has only 61.000 miles on it!

    My galant is blowing cold air, I have changed my antifreeze and all the hoses seem to be working. I think it might be the heating coil but I really don’t know where to start to find this out myself rather then paying someone. Can you help?

It is the heater control valve that is located next to your glove box the control valve has a motor atached to it take your glove box out and the lower part of the dash
then you can get to the part to replace it (Dealer item only ) around $150.00

I have a 2002 LS Galant. I had the clicking noise when I tried to turn the heat up and down. Then I had some noise when my fan was running. I noticed less air coming out of the registers. I will get to the point. I took it to a Mitsubishi Dealer. They charged me $85.00 dollars to check it out. They told me I needed and box that controls the temperature. It is under the drivers side next to the gas pedal. You can see it if you pull the piece next to your foot out from under the radio. It just pops out. You can changed the temperature and see the arm move from one position to the other. They told me I would have to also change my water hoses while they were fixing this part. The part cost about $900.00 dollars all together it was going to cost about $1900.00 dollars. I did not have them do anything.

I took the glove box out. I pulled the entire fan motor assembly out all together. When I finally got it out. I found that the entire motor and the heater coil was stopped up with insulation. They must have put the insulation on the inside of the fan box and duct assembly. When I cleaned everything the coil the fan housing out. I put it all back together. My fan works just fine now the temperature gauge works no clicking no rumbling just heat or cool air. The fan moves a lot of air now. They told me at the dealership that they had looked on there database file for anything that could cause this in my car. I can,t believe that this has not shown up on more 2002 or later galants. It was not easy getting everything out, but it can be done. Once you get it appart you will see how easy it is to put back together. It took me about 3 hours to do everything. I saved myself about $1900.00 dollars. And now it works great. I love my Galant I have had others. I put 440,000 miles on my 1992 Galant before it died on me. They are great cars. I hope this helps. Please let me know how you make out.

When I turn off engine, why do I hear a clicking sound from under dash?


HI THE CLICKING SOUND IS PROBABLY A HEATER/AC ACTUATOR WITH A STRIPPED GEAR , WHEN THIS HAPPENS TRY TO MOVE THE HEATER CONTROL KNOB FOR THE MODES (DEFROST/FLOOR/VENTS) SEE IF NOISE CHANGES . IF IT DOSE THEN THE ISSUE IS WITH A ACTUATOR UNDER THE DASH

Heater wont blow warm air


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

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

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


If not I would replace the thermostat.

I think I would just keep right on going until it quits.

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

No heat, heater core is good,blower moter works


Check the operation of the heater control valve. If it doesn't open up no heat. If the cable moves the control on the valve take the valve off and check it manually. The lever may work but the valve still doesn't open.

Hi my heater on my mitsubishi galant 03 heater isnt working before this happend we were hearing a clicking noise when we turned it to heat.


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.

When my AC is on the coldest setting I start to hear a clicking noise. Why is that?


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

02 galant heater not working


As me and my stepdad just discovered, the Galant came with an added feature to help the AC use less energy, by placing a heater valve within the dashboard. After pulling about 10-12 screws and half the dashboard apart, we simply opened the valve permanently. Many cars out there work that way all the time. Now after changing those lousy clamps into actual hose clamps by the firewall, my wife enjoys cool air in the summer and heat the whole winter. Hope this helps, there is a site that will actually show you a video of putting dash back together, as author did not film the disassembly.
