The 10-amp fuse responsible for my turn signals, clock, and instrument panels keeps blowing. What are some possible causes, and what might I do to fix this?

Is there any aftermarket bull stuff installed on the fused circut? even counting light bulbs

Do you use the cigarette lighter? The lighter itself can cause problem or if something is plugged into the socket

what are you doing before the fuse blows? using turn signal, lighter, etc.
