One problem related to sun roof has been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
In June of 2004, the sunroof of our 1999 Ford Expedition stopped working. We had to replace the entire track and motor. Now, just over a year later, the sunroof has stopped working. We are going to have to replace the entire track again. Of course, the warranty is no longer good.
