The heater isnt working, I heard a clicking sound coming from behind the dash board and now it only blows cold air...


The noise you are hearing is the blend door motor. It is a DC motor that moves a door in the heater box that controls the temperature of the air coming out of the box. There are two typical possiblities, one, the blend door motor is bad and two, the blend door is broken and the motor cannot move it.

Where is the heater control valve for a 2002 Mitsubishi Galant


The part you need is a dealer stocking part. There is an electric motor that turns heater core on and off. It's located under the dash to the left of the glove box. Some disassembly required. The part will cost about $120 to $180. part number is #MR958603. I saved money by purchasing it on line. It is a stocking part at most Mitsubishi dealers. Once you pull the glove box out and remove the bottom half of the dash all the way across, you should be able to gain access to the motor to replace it. Caution: if you do not put everything back in correctly and tie/tape it all back down carefully in the correct places you will have lots of under the dash noises when you are done. I do not think there is much chance for a recall on a car that is so old. It is not uncommon for an 8 year old part fail. Some Galant owners were able to get there cars repainted when the clear coat came off. But again, it is too late for the rest of us.

Temperature dial stopped working after I heard a plastic noise like a gear was stripping under the dash, i no longer can get heat from the vents


follow your heater core lines to find the position of the heater core some where near there will be a heat door the heat door is run by a small square thing about the size of a deck of cards it comes off and it also comes apart itself if youre carefull because if you got the wrong one /there may be up to 3 / look for shreded teeth inside the square thing is usually black and about the size of a deck of cards

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.

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.
