hey guys im having problems with my 94 g20 wipers. Now i have searched and seen a ton of people having issues with the pulse board and how hard it is to replace. my issues are similar but not at the same time. the wipers are random when they work but also the fluid pump is not working ether, correct me if im wrong but they are two different motors so it leads me to think it is the multi function switch over the wiper motor and pulse board. Am i wrong in thinking that? I dont know if i am capable of getting to the pulse board to replace but i assume it is expensive to have a shop do it.
