2001 TC- blows fuse #6- EATC circuit

2001 Townie- 60,000 miles. A very trouble free car. Today, the EATC display went dark, with no ventilation whatsoever. Fuse #6 was indeed blown. I replaced it. It very briefly all worked, then it blew again. Any ideas? It has had the blower resistor replaced some time ago but no problems until now. Is this a known problem on these cars? -Johnny :smile:
