Do you live in an area where the temp falls below freezing? If so is the fluid in your tank winter type. If not it may have frozen in the lines to the wind shield. Let me know. Thanks.

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.

I'm driving in rain, wipers working good, all of a sudden they quit! I drive for 15 min, check again, they work for a while, then quit again...what in the problem?


If your not familiar with automotive electronics an module control of components , I suggest you take it to the dealer . They have the tools to diagnose this type problem !

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.

Where is the fuse for the water pump for the window washer


A washer pump in a car's windshield wiping system moves washer fluid from a reservoir through hoses. The motorized pump pressurizes the fluid to allow it to be squirted from the hoses through nozzles onto the front and/or rear windshield of a car. The washer fluid helps windshield wipers get rid of rain, dirt, or other objects that can interfere with a driver's visibility. If your washer fluid is not being sent out when activated, the solution could simply be filling the washer system's reservoir with more fluid or cleaning the nozzles and hoses. In more severe cases, the washer pump may need to be replaced. Here are steps to troubleshoot a windshield-washer pump.

Windshield washer fluid doesn't squirt after windshield replacement


They probably knocked loose one or more of the tubes that carry the washer fluid. Try to trace the lines back from the sprayer nozzles and you may find the problem.

Make sure your washer fluid line that goes from the tank to the pump is connected.

1995 saturn My windshield washer doesn't squirt fluid. Which fuse should I check? What else should I look at?


This reply falls under, " what else should I look at."

When you press to squirt, do you hear any sound? if you do there are 3 easy things you can do.

1. Some of the windshield wiper reserviors, ( plastic bottles ), need a minimumlevel of fluid to operate, so, make sure you fill up your reservior.

If that doesn't help;
2. There is a very small hose that runs from the reservior to the pump, pull it off of the pump end, very carefully, and have someone hit the squirter.

If fluid comes through the hose;
3. Take a very small paper clip, straighten one end out, and push it into the ports that the water shoots out of to squirt the windshield.
Sometimes wax or debree can clogg these very little holes.

Windshield washer fliud does not squirt in my car


first try getting to a source of compressed air,with it regulated to a low pressure so as not to blow lines off blow into the top hole on the reservoir and force fluid thru the hoses,a lot of times the hoses or sprayers on the wipers get dirt in them and cant pass the fluid,also blow back thru the sprayers to see f this helps

My 96 Jeep GC windshield washer isn't squirting. I can hear it run when pushing the washer button and I hear fluid running ; but it doesn't spray on the windshield. Also , my wiper blade in the rear window...


your rear wiper motor might be faulty,in the front i would check your fluid level-if it is full and you hear the pump running-check your washer lines to see if they are pinched-usually around where the hood closes

Windshield wiper fluid won't squirt


When you pull the lever to activate the windshield washers, do you hear any type of sound coming from under the hood?  A whirring sound should be heard from the little electric pump that feds the washers.
If you can hear the whir, then you should look for a possible clog in the washer hoses (there is more than one...).
If you cannot hear the whirr, then you should check the fuse that protects the windshield washer circuit.  Check your owner's manual for the location and correct amperage for this circuit.
Good luck!

Windshield washers not working


I wouldn't worry about tracing the hose just yet, most likely it's a bad pump. Find the wire(s) going to the pump, usually on the bottom of the reservoir and connect a test light to a good ground. Then have someone try to 'squirt' the washer fluid while you touch the test light 'probe' to the pump's wire connector. If it lights but no fluid squirts, it's bad. They are cheap and usually very easy to replace. If it doesn't light there's a brake in the circuit somewhere. (bad fuse, bad connector, etc.) Good luck.
