First let me say I am mechanically stupid, I have a 05 Ram 1500 Big Horn w/48,000 miles, and all of the sudden my AC stop blowing hard it seems to be about 50% of what it should, it is still cold but not blowing as hard, the heat is the same way, I live in AZ so I am thinking the heat ruined it some how, has anybody experienced this with their truck or do dodges tend to do this, what could it be???

edit: it is now making a vibrating sound behind the glove box???
