how to fix the windshield wipers not working on Cadillac Escalade T1XX (2021-Present)

Symptoms

• Windshield wipers do not operate at any speed.
• No noise or movement from wipers when activated.
• Intermittent wiper setting does not function.
• Wiper washer fluid does not spray.
• Dashboard warning light may appear related to wiper system.

Diagnostic Steps

1. Check the vehicle's fuse box for a blown wiper fuse.
2. Use an OBD-II scanner to check for any related error codes.
3. Inspect the wiper motor's electrical connections for damage or corrosion.
4. Test the wiper switch for functionality using a multimeter.
5. Measure voltage at the wiper motor connector when the switch is activated.

Solution

1. Preparation

• Gather necessary tools: socket set, multimeter, OBD-II scanner, and a replacement fuse or wiper motor if needed.
• Disconnect the vehicle battery to prevent electrical shock.

2. Inspect the Fuse

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Identify the wiper fuse using the diagram on the fuse box cover.
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse; if it is blown, replace it with one of the same amperage rating.

3. Check Electrical Connections

• Reconnect the battery and locate the wiper motor.
• Visually inspect the wiring harness and connectors for any signs of wear or corrosion.
• If corrosion is present, clean the connectors with electrical contact cleaner.

4. Test the Wiper Motor

• Disconnect the wiper motor from its electrical connector.
• Set the multimeter to measure DC voltage.
• Activate the wiper switch and check for voltage at the connector.
• If there is no voltage, the issue may be with the wiper switch or wiring.
• If voltage is present, replace the wiper motor.

5. Replace the Wiper Motor (if necessary)

• Remove the wiper arms by loosening the retaining nut using a socket.
• Carefully pull the wiper arms off the splines.
• Unfasten the bolts holding the wiper motor to the vehicle using a socket set.
• Disconnect the motor from its wiring harness.
• Install the new wiper motor by reversing the removal process.
• Reattach the wiper arms and secure them with the retaining nuts.
