WPR fuse 25amp under hood fuse box .
Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• 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
This is more then likely not a fuse issue !!!!!!!
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.
Wiper motor low speed operation and the wiper PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
The PCB relays mentioned above are soldered right into the circuit board inside the fuse/relay block under the hood . There are alot of reasons for the wipers not to work ! The fuse could be blown but fuse's don't just blow for no good reason , short to ground , low resistance high current flow etc.... Intermittant !
Power and Grounds
With the ignition in the ON position, accessory voltage is supplied through the 25A WPR fuse to the WIPER PCB relay, the WIPER HIGH PCB relay and the WS WASH PCB relay that are all located in the underhood fuse block. Refer to Wiper/Washer Schematics.
G200 provides ground for the windshield wiper motor and the WIPER PCB relay. G100 provides ground for the windshield washer fluid pump and the windshield washer fluid level switch.
Highly doubt the fuse being the problem . If the fuse is blown ,that circuit has a problem , short to ground , wiper motor drawing to much amprage . Fuse's do not blow for no reason . Fuse # 18 -30 amp . under hood fuse box . There is also a relay , wiper on/off relay in same under hood fuse box . Also wiper hi/low relay ! There is also alot of electronics involved . integrated power module , front control module , plus C.A.N bus network . How to Diagnose Controller Area Network CAN . Could be wiper / washer switch , wiper motor , communication problem , module problems , Relay problem . Google chrysler intergrated power module . they have had a lot of problems with that thing .
It's the wiring ,there is a dead short to ground ! Looking at a electrical distribution chart that shows if that is the only system powered by the fuse , then isolating the circuit . It's not the motor or the pump , wouldn't blow the fuse unless it was on . Looking at a wiring diagram I see that fuse feeds power to the wiper switch through the accessory relay located in the under hood relay center . The relay could be shorted inside .
Troubleshoot the wipers. First disconnect wipers from under the hood. Replace the fuse. If the fuse still burns out then the problem is with the harness. There is a short in one of the wires and will need to be replaced.
If you replace fuse and it does not burn, then the problem is with the wiper motor. You can possibly just replace the circuit board or replace the whole wiper motor.
Look under the hood and unplug the blower motor. Then replace the fuse. It should not blow the fuse without the blower connected. If the fuse blows again there is a short before the blower motor. There are several Black power boxes, usually under the hood on the Drivers side, the A/C relay may be burned out.
If the fuse does not burn out, replace the Blower motor. You can get one from a Salvage yard or Autoparts place. If you still have problems and the Climate Control panel is lite, there is a self-diagnostic feature which is run by pushing some of the control buttons in a particular sequence.
The codes for this sequence is different from the Master computer.
It may also reveal problems only a Technician can fix. So try the Blower motor first, A/C relay second, and hopefully this will get you going.
One of your power wires is grounding to something, whether through a switch or relay.
I had wires fuse together that had the same effect in a vehicle years ago. Constantly blew fuses and happened to find the 2 wires fused under the dash in the steering console.
This is probably not your problem but there are very few things that cause those fuses to blow that rapidly.
Electrical is difficult to troubleshoot over the net though. Find out what the fuse goes to and try to follow the wires from point A to B as much as you can. May be as simple as a wire that the insulation is rubbed off or cut at a point and touching the body.
