Hi,
The 'stalk' that controls all these functions is faulty. Your truck SHOULD still be under warranty...Take it in.

Having windshield wiper/washer problems? Here are some more common problems.
The wiper motor is commonly replaced and was often not the problem. Don't replace the motor yet. maybe it's not the motor. It could be a fuse or something at the wiper switch. The wiper motor has two windings, fast and slow. The wiper switch sends a ground signal to each motor winding. More often, there are problems with the relay, or at the wiper switch, or in the cable to the motor.
Don't be too quick to replace the washer pump. The problem is often just a clog in the sprayer heads. You can clean out the sprayer holes with a needle, some have two holes, so look closely. Hope this helps.

Sounds like you have a bad switch assembly. Is yours the type that the wipers/ turn signals and washer operate all on the same lever? the turn signal switch ? If so that is most likely the problem.

I've seen this problem before.
First check the fuse.
Second check to make sure the motor has a good ground. Easy way to do this is to take a wire and run it from the (-) negative side of the battery to a metal part of the wiper motor, be sure it is to bare metal as current will not flow through paint.
Third if the wipers still don't work, a voltage check is needed at the electrical connectors on the motor. This can be done with a voltage meter. Try every speed on the switch. If different readings are noticed at different speed settings then it's the motor.
Fourth if you notice no differences then it is probably the switch unless there are corroded or broken wires somewhere in the circuit.
Good luck and keep me posted

Circuit/System Description
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation. The windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .

2011 Dodge Ram, 2500, Diesel. I had this exact same problem. I initially checked all fuses and they were all good. I then disconnected the negatives on both my batteries for 10 minutes and hooked them back up. The problem went away and all has been working for a couple days now.
