My sable with auto temp control puts out nothing but hot air. No matter what you set the temp at you get heat. When you vary the temp setting the blower speed goes up and down as it should. I checked the evaporator return line, its ice cool,.and the comp clutch is engaged. I figure its either the mixing door or what ever controls the door. Does anybody know how the door is activated[elect or vac], what controls it and how hard is it to get at. Where can I get a good detail manual on this car.
Any help is appreciated Thanks
