i recently noticed that my clock was resetting itself so i did a search and found that i should replace the "back up" fuse 7.5 so i did that. now the clock works but it stays on even after i turn off the car. i was pretty sure that i had gotten the right fuse, i know it was 7.5, the same color, and the little squiggly metal line looked the same, and it was in the "japanese car" fuse replacement set. is there anything that i might have missed? any ideas on how to fix it?
