It can be faulty wiper motor or blown wiper control fuse.


Do you hear any kind of noise when you starter the wiper function. If yes then fuse is ok, but issue is wiper motor.

If no movement at all and no noise then its blown fuse or shorted/loose wiper control wiring: -----

Looking for the fuse for the wiper motor 2008 chevy impala


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.

Why is my windshield wipers running in the off position, it's like they are running in the intermittent position, but it's in the off position.


When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

My windshield wipers do not turn on


Hello,

Check you fuse panel. This would be the easiest way as it's either the wiper motor, wiper switch or a fuse. Your car should have a schematic of what fuse is for what function, if not you can Google it. You can also pic up a repair manual for about $15-$20 at any local parts store too. Parts are pretty cheap and it's probably the fuse or the interior wiper control switch as wiper motors rarely ever die. Good luck.

I have a 2007 mustang an the wipers wont turn off I had 2 pull the fuse to turn them off can u help me


The windshield wiper motor is a smart wiper motor with an integrated electronics module. The internal components of the motor are the high/low relay, washer pump relay, and the run/park relay and associated electronics.
The windshield wiper motor receives its inputs from the windshield wiper/washer switch. These signals are ground reference signals. When the switch is placed in different positions, various input signals are selected and sent through circuits to the motor. The windshield wiper motor module identifies these selected input signals and activates the motor to the selected function.!
Your probably going to need a new wiper motor ! ! ! But you should always test before replacing parts !

Need a diagram for a windshield wiper motor for 1997 firebird


I have a 97 Firebird that has this issue. Sometimes when the wipers are used (number of passes makes no difference) they stop in the non-parked position. I've studied the schematic and will remove my motor one weekend and check the park relay soldering and contacts if it has a removable cover. I suspect that when the wiper switch is turned off the park relay is failing to allow the wipers to park.

I have checked the wind shield wipers motor to try to find out what is shorting out the fuse. Where could the short be located that is causing the wiper fuse to blow?


You need to isolate the problem by disconnecting the windshield wiper motor. If the fuse does not blow with the wiper motor disconnected the problem is in the windshield wiper motor. If the fuse still blows with the motor disconnected, there is a 12 volt wire shorted to the frame. You will most likely need a set of wiring schematics to trace down the short.

Ware is the wiper module located on a 2000 crown victoria


Follow the Dark Blue/White wire or Brown/White wire from the Multifunction Switch to the wiper module according to the schematic.
Also, one can trace the wires from the windshield wiper motor to the wiper module by peeling away the wiring loom and looking for a Yellow/Red wire that leads to the module.

Damn dealers. No schematic needed. Open your hood. Just below your windshield you will see vents and through those you will see your wiper motor and arm. You might need to replace the bushing which is probably what broke.
