We got this car a few months ago. Runs like a top and get 33mpg and has 233K miles. However, now that it is cooling off the heater blows a small amount of air but comes from all vents. Not warm air or hot, barely even room temp. But slightly warmer than the rest of the air. When we push the buttons to control where it goes it doesnt matter, just keeps coming from all over. I was told by the local subaru dealer that the part would cost over $400 to replace the Heater Mode Control Module. The car just isnt worth that but we need some sort of heat. Any suggestions as to what to try I just dont think the module is failed. I know it is vacume controled. Looking for any help at all. Thanks in advance.:-\
