Rear Wiper/Washer System Components
The rear wiper/washer system consists of the following components:
• Rear wiper/washer switch
• Window wiper module-rear
• Window washer pump-rear
• RR WIPER 15A fuse
• RR WPRB 25A fuse
Rear Wiper/Washer System Operation
The rear wiper module controls rear wiper motor operation. Battery voltage supplied to the module is used to operate the wiper motor in all modes and to return the rear wiper arm to the park position after the ignition is turned off. Accessory voltage supplied to the rear wiper/washer switch is used to supply the rear window wiper and washer switch signal circuits. In wiper switch positions 1 and 2 the wiper switch signal circuit voltage level to the wiper motor module determines the wiper motor delay interval. The rear window washer pump supply voltage circuit is used to provide the operating voltage for the rear washer pump for as long as the rear washer switch is pressed. The rear window washer switch signal circuit is used as a wash signal to the rear wiper motor module to operate the wipers during the rear wash operation.

Hi Bruce ,here's a link showing you how to replace your pump motor. SAVE 20 ON ONLINE SHIP TO HOME ORDERS OF 100 OR MORE Here's a video to watch, How to Replace Windshield Washer Pump Dodge Caravan DIY

your sprinkler motor needs to be replaced. sprinkler motor is located right below the windshield washer reservoir

What happens when you push the washer for the front? if this van has a frt and rear washer then there should be two buttons for the washers, if this van has two then i have seen where the pumps where connected backward so the frt sprays in the rear and the rear spray to front but again this is for dual window washers, as far as the back rest you will need to do some testing, you wiil need to test the switch for the back rest and see if its a bad switch or motor, good day.

Possible there is fault in the cluster switch , possible that the switch is not contacting according to the intended function to power the front washer and rear washer motors.
You need to check the output or using a multimeter the switch continuity of the wiper cluster switch.

The spray nozzles may be plugged.

follow the hoses to the hood or wiper arm (i dont know where your spray nozzles are)and disconnect hem and press the spray button. if it sprays your nozzles are plugged, if not its your pump motor.

Check the hoses running to the front windshield washer nozzles. If the hoses are good check the pump to see if it is working correctly. Remove one of the hoses from the spray nozzle and see if the pump is working. If it is then the spay nozzles are stopped up. Use a needle to clean them out. They can easily get plugged with wax. If the pump is not working then either the fuse is blown or the pump is defective.

If you get flow with the hose disconnected it is likely that the nozzle is plugged.

front pump motor may have come out of washer bottle it is only held in by the seal no bolts
