1986 K5 Blazer


Wipers work well on low or high, but I have no delay, even though the truck came stock with the delay option. I ran through the manual's troubleshooting tree and it told me to replace the delay module. I'm always one to try to repair rather than replace parts, so I disassembled the delay module. One of the circuits on the board is burned out. It should be easy enough to replace, but I can't identify the burned part. Can any of you electrical engineers out there identify the burned part on this picture?
