    I have the same issue, sometimes though no heat would flow through, so I would have to ride with heat knob turn on for awhile then eventually it would flow.

    After doing some research on the issue the answer to your problem that I found online is the Motor switch valve for your heater. basically behind your glove box their is a motor that control the heater valve for the heater core. basically your the motor is going bad and needs to be replace. How the motor work is like this- the hot coolant from the engine is suppose to flow to your heater core (which looks like a smaller radiator) their is a fan back ther as well that blows at the heater core that is obviusly hot, thats your hot air. basically the noise you hear is the motor switch trying to open the valve for the coolant to flow to the heater core. if the motor switch is not opening the valve then no hot coolant is being sent to the heater core to blow hot air.



    Unfortunately if your not a mechanic or skilled auto tech, replacing the motor yourself is not a self option since you might have to disassemble some of the dash board to get to the motor switch,



    pardon me if the name of part is not exact, i could not find the exact website where i found this info. but basically that sound your hearing is a defective motor that controls the flow of coolant to your heater core. you could try navigating through this website to give more info on how the colling system works http://auto.howstuffworks.com/cooling-sy.... unfortunately I did not fix this particular problem form my car since I have a more sever issue going on at the moment, when i turn my a/c on its stalls my car so I'm trying to fix that problem now

    Ditto. When I was in to deal with another problem, a mechanic told me the problem was with the stepper motor, which moves the function between heat and A/C. And would have cost me an additional $300 to fix/replace. I didn't do it at the time, and I likewise just ride with the wrong one going until the dash makes that ticktickticktick noise and it changes over. I suppose one of these times it's simply not going to change over and I'll actually have to get it fixed.

    I am having the same problem. I never hear the clicking sound though and get nothing but cold air when the dial is set to 'Hot'.

    yep-mine does the same thing. when you switch from hot to cold, it sounds like there's a gremlin in the dash dancing around! haha! it will **** when it really does break.

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.

These problems can be caused by a blocked heater matrix which is basicly were hot water from your engine goes into your heater matrix behind your dash boared if this is blocked then it can cause your heaters to be faulty my advice is go to your local garage and ask them to flush your heater matrix

Temp knob clicks from hot to cold air conditioning only works sometimes


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.

My 2004 Mits Galant air conditioning is not working correctly. First of all, when the AC level is on 1 or 2 it doesn't blow at all. It blows on Levels 3 and 4, however the air is not cool at all. It is...


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

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.

Overheating and heater blowing cold air.


Heres the answer for the clicking sound

Temp control problem


I just repaired my 02 Galant with same problem. I removed the heater control box and disassembled and applied 12 volts dc and verified motor was ok. Then attached the plug back on and checked in car still not moving. Removed the screw holding the temp. control and cleaned contacts and applied pro-gold contact cleaner and preserve re-assembled and heater works like a chame. Saved 400-500 bucks and we have heat. About 2 hours labor to remove bottom part of dash and troubleshoot.
