Location of windshield wiper relay on 2005 Chevy Tahoe

The windshield wiper relay on a 2004 Ford F-550 is typically located in the fuse box under the hood. The fuse box is usually located near the front of the vehicle, on the driver's side. To find the windshield wiper relay, you will need to refer to your vehicle's owner's manual or a wiring diagram for the vehicle. The owner's manual should have a diagram of the fuse box that will show you the location of the windshield wiper relay. Alternatively, you can search online for a wiring diagram for your vehicle.

Once you have located the fuse box, you may need to remove a cover to access the fuses and relays. Look for a fuse or relay labeled "wiper" or "wiper relay" to find the windshield wiper relay. If you are having trouble finding the windshield wiper relay, you may want to consider consulting a mechanic or taking your vehicle to a dealership for assistance.

try taking off the neg battery terminal for 30 minutes then replace it try wipers.

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.

The is the symptom of a defective wiper switch.

Watch the video, I know it is a GM truck but the procedure is the same for any GM vehicle. How To Install Replace Windshield Wiper Transmission Linkage 2000 06 Chevy...

Most all replacement blades are a multi-universal fit...the replacement blade packaging usually shows many ways to change depending on the model...However, many of your larger Auto Parts Stores like Autozone, OReilly, and Advance will actually change the blades for you...(you can watch) as long as you buy their replacements...Higher price alone does not mean a better wiper blade replacement...depending on your location...my preference is "Winter Blades"...these replacement blades arms are covered with a rubber boot, that reduces ice and snow sticking to metal arms:) Great safety and vision help for your 2002 Tahoe:)

the relay that runs the motor

Check the fuse for windshield wipers, that's the first point you can start looking for fixing the them.

There is a bar that connects both your windshield wipers together check that to see if it is broke or has come unscrewed. Should be underneath the hood upagainst the firewall.
