Hello,
I have had this problem recently with my 2003 Windstar Sport. Just the other day the #6 fuse had blown. This runs the radio, and the power sliding doors plus the remote locking/unlocking controls.
I replaced the 15A #6 fuse and instantly it blew as soon as I inserted it in. I decided to try again and disconnect the battery first. It seemed to work, but as I was resetting the clock I heard a click and it blew again.
If anyone has a solution or knows of why this may be happening, any help will be appreciated.
Thank you, Steve
