I'm not the least bit familiar with your after-market intermittent module.. But I do know how the wipers work in factory form. The wiper motor has voltage applied to it whenever the ignition switch is on. The wiper switch provides the ground path when it's turned on to either speed position. Here's where the assuming begins.. I assume the intermittent module provides the "final" ground path and has voltage applied to it also. The module has probably failed and has developed a short to ground. Removing the wiper fuse removed the voltage to the wiper motor and it stopped. The module still has voltage applied to it and has "self destructed".. Try removing the module from the circuit and I bet your wipers will function as designed from the factory..
