2004 Chrysler Pacifica a/c doesn't blow any air in front vents, only defrost works A couple of weeks ago, the fan stopped blowing any air in the front. No cold air goes to the back, but if I turn on the defrost and lower the temp it is cold. Also, the front floorboard vents are blowing cold air, too. Please let me know what you think this is, and if it's a cheap fix or something bigger!

This is generally caused by a loss of engine vacuum to the AC door motors. The first thing to do is pull the AC control panel and see ifone of the hoses at back are getting any vacuum from the engine while it is running.
