Hi, my name is***** 9 also powers the headlight wiper motors through the K30 terminal on the headlight switch. Your short could be at either wiper motor or at the instrument cluster/dash light circuit or at the license plate lights. I'd try disconnecting the headlight wiper motors and see if the fuse still blows. If it does the next step would be to disconnect the instrument cluster.
Let me know what you find out.
