Hello and thank you for your question, the AC system on your Explorer is designed to divert to defrost when the control panel looses vacuum and in most cases this type of problem is caused by a systems vacuum leak. In order to determine the source of the leak you are going to need to do some testing, are you able to do the test and are you working on a Duel climate control system or a manual system?
