Four problems related to ignition module have been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
1999 Ford Expedition. SUV has been random electrical anomalies over the past month from today. Gauges, interior fans, and lights would stay on when the ignition would bee in the off position and key removed. Upon inspection from a local Ford dealership service department, it has been noted from them that corrosion of the general electrical module and fuse box are the cause, most likely from a water leak from the front windshield. Improper information from dash consoles can lead to stalls on roadways or improper driving due to improper information received from the instrument panel. In my case, it is limited to battery drain, improper fuel readings, windshield wiper failure, and failure to start. In the end it is mainly a resemblance to odi complaint ea05-015.
Car on board computer had to be replaced.
