We have a 2004 Chrysler Town and Country Limited, approximately 160K. Recently, the air conditioning started working intermittently - or not working intermittently, depending on how one looks at it. When the van is first started, it will blow cold air. More than once, switching to the recirculate setting has affected the function. But at other times, it will just stop blowing cooled air and blow swampy, warm air.
Sometimes, after a “rest” it will work again for a while. The Freon was found to be low and charged and dye placed in the system. It seemed OK for a few days. Now, back to intermittent cooling. I suppose the Freon could be low again? What else might affect the function of the air conditioning in this say?
