Unfortunatly the fuse could be blowing for a million reason. Including a shorted wire to a bad seat motor. My dad owns a auto shop and he is one of the best wiring wiring people in a reason. We had a Isuzu come in and every time it rained the fuse would blow. When I towed it in it would be dried off. So we'd replace the fuse and it would be fine! Finally after 5 tows we waited untill it rained and drove it till the fuse blew. Then we jumped the fuse with a wire went up in smoke. Here one of the wires in the harness under the car rubed through in a hiddedn area. We ran a new wire andit was fine!
So unfortunatly it could be nearly impossible to find the short. Might want to get a box of fuses
