my a/c would blow cold for about five minutes then cycle to blowing not so cold. since i know nothing about a/c my dad told me to take it to firestone. about an hour later i got a call saying it was blowing cold as could be. so i go up there to find out what the problem was. mud was caked in my a/c condenser and radiator causing it not to get proper air flow. so 80 dollars later in labor it is blowing cold cause they hosed it out just thought i would write this up so people could try this before taking it too the shop.
