what was vapor coming thru vents
while driving on the highway with the a/c on, I noticed vapors/mist coming thru the vents for a brief time. The a/c still works but is noticeably cooler. What caused this?

    the vapor is being caused by the the receiver dryer malfunctioning. it is designed to take the moisture out of the system so no water vapor will be blown through the vents. have the receiver dryer replaced and also the orafice tube with this procedure.
