Need help?
Do you have a question about the Explorer 2003 and is the answer not in the manual?
Questions and answers
Where is the Body Control Module located I have been told different location's and I have not found it to take out
A warning sound happens every so often when I drive. It is not the seat belt sound
A warning sound in a 2003 Ford Explorer that is not related to the seat belt could be caused by the ABS warning lamp. The ABS system momentarily illuminates when the ignition is turned to ON, and if there is an issue with the system, it may trigger a warning sound. Additionally, sudden vibrations, such as a collision when parking, could activate the fuel pump shut-off switch, which may also cause a warning sound.
