My A3 is cutting the panel fuse

[lwen]

Yesterday my car suddenly cut the panel fuse (5 amperes). I changed the fuse more than 5 times. Nothing was done to happen to cause it, and not always occurs. The panel still works when change the fuse and randomly it cuts (1 minute to 1 day). Does it happened with you? What it could be?
I changed to a stronger fuse (10 A) but still cut...
