Lost my windshield wiper

Do you know how to test automotive electrical circuit's using a DVOM - digital volt ohmmeter ? Do you know what a wiring diagram is an how to read one ?

Under system click on body & accessories ,then under subsystem click on wiper/ washer's . Click the search button then the blue link.

Windshield Wiper/Washer System Components
The windshield wiper/washer system consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor
• Windshield washer pump
• Windshield washer relay
• Outside moisture sensor
• FRT WIPER 25A fuse
• W/S WASH 15A fuse
Windshield Wiper/Washer System Operation
Accessory voltage and ground is supplied to the windshield wiper motor and provides the power for operating the wiper motor and logic power to the wiper motor module. The WASH, MIST, LOW, and DELAY modes are controlled by the windshield wiper/washer switch through a series of internal resistors. The windshield wiper switch supply voltage circuit is a 12-volt reference from the wiper motor module to the wiper/washer switch, and the switch position determines the point on the resistor assembly where the reference voltage is applied. The windshield wiper switch signal 1 circuit supplies the voltage from the resistor assembly to the wiper motor module and the signal voltage determines the operating mode. High speed operation is controlled by the windshield wiper/washer switch through the windshield wiper switch high signal circuit. The windshield wiper switch high signal circuit is supplied 12 volts by the wiper motor module and when the wiper/washer switch is turned to the HIGH position the windshield wiper switch high signal circuit is grounded through the switch ground circuit. The windshield washer pump is controlled through the windshield wash relay. The windshield wash relay coil and switch is supplied battery positive voltage, and during WASH mode the wiper motor module grounds the washer relay control circuit energizing the relay. When the relay is energized battery positive voltage to the switch side of the relay is supplied to the washer pump control circuit.

check to see if security system is working (activeated) ,look at fuses

Rear fuse panel (under rear driver's side seat) fuse #33

There are only to things which could cause this.The wiper motor cover or the switch itself.Which is part of the multi-function switch.The cover is cheaper.It is located under the air inlet grill.The cover is on the wiper motor itself.There is a circuit board on here that causes this problem.It is the part you need to replace.Hope this helps.Good luck.

It sounds electrical. I would check your fuses.

Check fuse #9 in the rear fuse panel.

the park circuit in the wiper motor is bad, or the live to it is there should be a constant live to wiper motor, if its good replace wiper motor

windshield wiper, u'l nid to check the fuse if its burnt and has to b replaced

As it turns out, there is a recall On 2002-2003 Chevy Trail Blazer's
Windshield Wiper/washer
NHTSA No. 04V046000
Recall Date: Feb, 4th, 2004
Call your dealer to see if this is still under the recall to be fixed.
RECALL: 2002 - 2003 Chevrolet Trailblazer NHTSA Campaign Number: 04V046000 www.nhtsa.dot.gov
Manufacturer GENERAL MOTORS CORP. Recall Date: FEB 02, 2004 Potential Number Of Units Affected: 581394 Description VISIBILITY:WINDSHIELD WIPER/WASHER Summary CERTAIN SPORT UTILITY VEHICLES HAVE WINDSHIELD WIPER SYSTEMS THAT WILL NOT TURN ON, CEASE OPERATION WHILE IN USE, FAIL TO TURN OFF/ON BY THEMSELVES (MOISTURE SENSITIVE WIPER SYSTEM), OR HAVE CONTINUOUS WINDSHIELD WASHER PUMP OPERATION BECAUSE THE PRESENCE OF WATER WITHIN THE WIPER MODULES CAN EITHER CAUSE A SHORT CIRCUIT OR CAN LEAD TO THE CORROSION OF COMPONENTS WITHIN THE MODULE. Consequence DEPENDING ON THE OCCURRENCE AND WEATHER SITUATION, DRIVER VISIBILITY COULD BE REDUCED, WHICH COULD RESULT IN A CRASH. Remedy DEALERS WILL COVER THE WINDSHIELD WIPER MODULE VENT HOLE WITH A PATCH. ALSO, THE WIPER MOTOR, CIRCUIT BOARD, AND ELECTRICAL CONNECTOR WILL BE INSPECTED TO SIGNS OF WATER INTRUSION AND/OR CORROSION AND BE REPLACED AS REQUIRED. THE RECALL BEGAN JULY 6, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438; OLDSMOBILE AT 1-800-630-6537; OR GMC AT 1-866-996-9463.

then it has to be the switch or the motor.
