What fuse controls door chime on 2003 ford expedition?

There isn't a dedicated fuse solely for the door chime on a 2003 Ford Expedition. The chime's power is usually integrated into a larger circuit, often related to the body control module (BCM). A problem with the chime is more likely to be a BCM issue or a wiring problem than a blown fuse.

To troubleshoot, you should:

1. Check the owner's manual: Your owner's manual should list all fuses and their corresponding circuits. Look for fuses related to the body control module, interior lights, or the general instrument panel. A blown fuse in one of these areas *could* affect the chime.

2. Inspect the fuses carefully: Even if the fuse appears intact, it might be internally broken. Replace any suspect fuses (even if they look good) with fuses of the correct amperage.

3. Consider the BCM: If all fuses are good, the problem is likely within the BCM or its wiring harness. This requires more advanced diagnostic techniques, possibly involving a scan tool to check for codes.

4. Check the door switches: Ensure the door switches are properly working and making contact when the doors are opened and closed. A faulty door switch could prevent the chime from sounding.

In short, while a blown fuse *could* be the cause, it's less likely than other issues. Start with a thorough inspection of the fuses related to body electronics, but be prepared to consider more complex problems if the fuses are fine.
