Hello and thank you for your question,

The common cause for the #15 fuse to blow on the 2001 Expedition is in most cases due to a shorted Brake Pressure Switch located on the master cylinder. Disconnect and inspect the connection of the brake pressure switch on the master cylinder for signs of brake fluid on the connection which may have leaked through the switch and down the wire into the speed control servo connection. If brake pressure switch connection is wet with brake fluid, unplug and inspect the speed control servo connection for signs of brake fluid as well. The presence of brake fluid in the servo connection could cause fuse 15 to blow when the brake pedal is depressed due to the brake input to the servo getting grounded out.
