Again, this electrical manual is for the 93 suburban ,yukon and others...But here's the wiper section in case it helps. Sorry if it's out of focus.. I'm guessing there are maybe more relevant manuals here on the site too..Update on wipers:
I was able to finally diagnose it is likely a grounding issue. I hard grounded the wiper motor case to the body and it worked completly normal. I also pull tbe connector for the wiper sprayer motor and hard wired it and it worked well. I am not exactly sure what I should be looking for now or how to fix this. I tried to follow the ground for botb and they lead into the cab under dash.
