Ok, so one of my 20ma fuses keeps blowing recently. It is the one that controls the HVAC and guage cluster lights, and i think it also cuts out the turn signal lights when the headlights are on. It has blown 3 times in the last month, and i've never had a problem with it before, and i haven't changed any wirring in my car lately. Anyone have any idea as to why this may happen? Or how to fix it?

TIA
