LMFAO1) Remove dead rodent from your dash vent system.
Check whether your the condenser fan (driver's side) runs when the A/C is on.I got a similar problem, mine is that at first it blows hot but cools down when I drive for some time and everynow and then a fan behind the glove box makes a huge sound like its a lawn mower, any suggestions?
Well, at least there's probably something frightening in those vents.LMFAO
