I could see a play being the issue. A fuse doesn't work then "fixes" itself. I contact getting nasty on a relay can, even sealed ones. The ECM isn't that hard to get to.
F-2 Speedy this is what I found with the fuse, should I be concerned with the situation, not sure why it would melt and not just blow the fuse unless it was a loose connection on the fuse holder
ya you need 10 posts to post pics and links.........check the fuse size it may had been replaced with a higher amp fuse which is a no no and could cause a fire
