If critters have not moved in, check the ductwork under the dash. Something may have come loose and the air is not being directed to where it should be. One other possibility is the air conditioning may be stuck on a freezing up the cooling coil under the dash. This will usually be noticed as an airflow drop off to nothing though. Look for frost on the air-conditioning system hoses under the hood. HTH. - Jim
