From the manual, page 4-14 (2004 model)JBENSIN26 said:I'm glad I stumbled across this posting. I was just getting ready to call the dealer and try and have them identify the problem. I thought that my A/C was stuck on! It was just as you noted, I turned on the Defrost for five minutes and then turned it back to vent and the cold air was just pouring out. I couldnt figure out how to turn it off. Is there a fix for this?
