rear wiper continously works

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

thanks for any help

What year and model of xj..?

try swapping switches. if that doesnt work, i would think its a short somewhere.

To shut it off, pull up on the switch.

its a 1997 cherokee sorry i always forget that, also it doesnt turn off when i press up on it i meant to say that.
