1997 Audi Quattro 6 cyl Four Wheel Drive Automatic 180000 miles
FUSE #7(license plate, glove box, air cond display, ashtray, instrument cluster) 5amp blows as soon as it is replaced. Tried 15amp, 20amp & 30amp with spark/blowing of fuse. Cannot see any black/charring on wires from fusebox. Problem went from intermittent to constant in 3 months. Pops/sparks when fuse blows. Do I have a short i(wires touching)in dashboard? Blown lightbulb also?
