What fuse cause speedometer and power outlet not to work on ford windstar?

In a Ford Windstar, a blown fuse can cause both the speedometer and power outlet to stop functioning. Typically, this issue may be related to the fuse for the instrument panel or the accessory power outlet, which is often located in the fuse box under the dashboard. Checking the owner's manual for the specific fuse numbers and locations can help diagnose and resolve the problem. If the fuse is intact, further electrical issues may need to be investigated.
