There are several things that might cause it. You may have to get somebody to check manufacturers codes, see if anything pops up.
There is an on/off front wiper relay in the integrated power module. The voltage to both the load and control side of the relay are hot all the time. The ground circuit for that relay goes to the ipm. There has to be a request or the circuit won't ground. The IPM--BCM--front wiper switch--wiring circuits are all involved.
There is a fuse 4, 30amp, if you pull the fuse, it should stop the wipers from coming on, until you can get it fixed.
