When I turn temp control from cold to hot , cold air still comes out until i hear this clicking noise from under the dash. Sometimes it will come on and when it dose;nt I turn off engine and start up again sometimes this works. thank you scott
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

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.
