I had to disconnect my rear wiper switch because for some reason when plugged in it continously works, its not fast it just wipes then waits a second then wipes again. Then when i try to press the button to stop it, it sprays the fluid. the pigtail doesnt have to be fully plugged in for it to do this if i just lay the pigtail in the back of the switch it works. Im thinking i have a dirty connection or...? Anyone have an idea? It jsut randomly started doing this. I have searched and no one has the problem i am having
