I have the 4 Cyl Mitsubishi Galant 2002. (In fact it was probably made right her in Bloomington/Normal IL) I seem to be in the same boat as others - sort of... My temperature dial will not open the heat although the AC works fine. For as long as I can remember there has been the grinding noise when the heat did work and it was opening something up. It actually sounded like a door trying to open. It does this off an on but recently I have not been able to get it to heat for several weeks. I have read the posts about the MR part that may the problem so I decided to go to autozone to see if I could buy a Haynes that would show how to get to it. Before I went, I took the neg side off the battery and pulled the bottom panel off under the glove compartment. I went ahead and took screws out that I could get to around the blend door box type thing and that's when I decided I better get something more on how to dismantle things.
On the way to autozone, I turned the center dial to mode 1 on the fan control and then moved the dial to heat for the fun of it- THE DARN THING WORKED! I'm afraid to see if it will do it a second time so I went on to the store. The Haynes manual DOES NOT show the MR part mentioned in other posts nor does it show anything about the Blend Door and what you might be able to do as far as lubricating them and accessing it. The sales person there agreed that it may be that the blend door is binding up and not opening for heat but neither of us could find any info about it.
My questions:
1. Does anyone know where I can find pictures/instructions on the Blend Door area?
2. Anyone else got the same problem and been able to solve it?
