Its getting to the point where I have to defrost the windshield in the morning when I leave for school. Where should I start looking if it smells like something died withen the heat system?

 

in the heat system.

 

It could just be fungus or rodents moved in. Anyway, there is sprays you can buy at parts stores that are supposed to get rid of the smell.

 

[&:][&:] sounds like a rodent may have taken up residence in your ride. the little bastards **** and **** right where thay sleep and occasionaly die in the same spot. the blower moter is usually the easiest spot to access the largest portion of your heat and ac system and ive found more than one of those little ****s using the hamster wheel/ blower wheel for its home. if no sign of rodents is found a bleach solution or store available solution may be used to clean the evaporator core(mold and stinky stuff can collect here)
