So in my 2003 dodge ram the ac was blowing cold but couldn't feel it. I found that door that switches from outside to inside air was broke and was just laying there blocking the air so I took it out and blows hard. So now it's about to get cold where I live and I want the truck to have heat obviously. The thing is is that the heater never really gets warm it just blows cool air for some reason. With the air coming from outside will it ever get warm during the winter? Do I have a heater problem and need to somehow block off the air from outside coming in??? Thanks!
