You have two problems. The first is the wipers turn off and stay in the upright position and do not close. The motor is fine. There is a steal 'close' tab that has been bent out of position. You just need to push the steal tab back into position. You can use a chisel or screwdriver to pound it back into the 90 degree position.
The windsheild washer motor probably needs to be replaced

I had the exact same problem PLUS my power door locks and some guages stopped working. I replaced the Body Control Module (BCM) which is behind the inside fuse box and problem was fixed. I did get the part from a salvage as the unit from Dodge was $1000. Make sure you replace with same part number and disconnect battery before working on it. One downfall of changing BCM is I now have a new odometer reading.

If your car is under 36000 miles take it to your dealer and have it fixed under your warrenty. All of your interior electrical systems are controled by computors and sometime not a simple repair ! The dealer has the tools to monitor different switch states to aid in isolating the problem. Just guessing if its a switch or a computor or a wiring issue can get very costly.

replace relays 30 & 32 in the engine compartment fuse box near the battery. they both control windshield wiper function. there are a group of six relays near the back of that panel..... looking at the group from the front it's the two relays on the left starting from the top one and going to the next one down.
Please take a moment to rate this solution thanks

Body control module (BCM)
Wiper PCB relay
Wiper high PCB relay
Windshield wiper motor
Windshield washer fluid pump
Windshield washer fluid level switch
WPR fuse 25 A
WSW fuse 10 A
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
High Speed Operation When the wiper switch is in the high speed position, ground is applied through the windshield wiper switch high signal circuit to the body control module (BCM) indicating the wiper high speed request. In response to this signal, the BCM then energizes the wiper PCB relay, as stated above, and the wiper high PCB relay by applying ground through the control circuit to the coil side of the relay. With the wiper high relay energized and its switch contacts closed to the high speed control circuit of the wiper motor, the motor will operate at high speed.
Wiper motor high speed operation and the wiper high speed PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.

DTC B3922 00: Front Wiper Function Select Circuit
You could Have a switch problem , BCM problem ,PCB relay problem , the pcb relays are non serviceable an the whole under hood fuse box would need to be replaced . Malfunctioning motor bad ground some where etc.....
