To find the correct fuse:
1. Consult your owner's manual: This is the best resource. The manual will have a fuse diagram showing which fuse controls the audio system. Look for labels like "Radio," "Audio," or something similar.
2. Check the under-hood fuse box: This is the most likely location for the main audio system fuse. The fuse box cover usually has a diagram showing the fuse layout and what each fuse controls.
3. Inspect the in-dash fuse box (if equipped): Some Ford Expeditions might have a smaller fuse box inside the cabin, possibly near the radio. Check your owner's manual to see if this is the case for your vehicle.
4. Check the radio's internal fuses: If the main and in-dash (if applicable) fuses appear good, you may need to remove the radio itself to access any internal fuses. This requires some disassembly, and it's best to refer to a repair manual or consult a professional if you're not comfortable doing this.
If none of these fuses are blown, the problem isn't likely a fuse issue but rather a problem with the CD changer itself, the wiring, or the radio head unit.
