2nd Gen Non-Engine/Transmission Wiper fuse keeps blowing

[JJRSMP12]

1999, all of a sudden my wiper fuse blew. Put new ones in, they blow instantly. I pulled the relay for the wiper to rule out the motor causing the short, but it still blows. I took the steering wheel harness off and looked at the wires, and they looked ok. Does anyone know the exact colors for the wiper? Also, any ideaS? Thanks

Dealer says it is the wiper control module. Aound $100 + installation. Already have 1. 5 hours in diagnosis of problem. Is this an easy fix if I purchase the module from somewhere else and put it in myself? Or is this something I should let them do. Thanks
