Fixing Windshield Wipers That Won't Turn Off in a 2020 Chevrolet Silverado 1500 T1XX

Tools Required
  • OBD-II scanner
  • Multimeter
  • Screwdriver set (flat and Phillips)
  • Wrench set
  • Replacement wiper relay (if faulty)
  • Replacement wiper switch (if faulty)
  • Wire connectors (if needed)
  • Electrical contact cleaner
Repair Instructions
Step 1: Disconnect the Battery
  1. Park the vehicle on a flat surface and turn off the ignition.
  2. Open the hood and disconnect the negative battery terminal using a wrench to prevent electrical shorts.
Step 2: Inspect the Wiper Switch
  1. Remove the plastic cover around the steering column using the appropriate screwdriver.
  2. Disconnect the wiring harness from the wiper control switch.
  3. Using a multimeter, check for continuity in the switch by flipping it through its various positions (off, intermittent, low, high). No continuity in the “off” position indicates a faulty switch.
  4. If the switch is faulty, replace it:
    • Remove the switch from the column.
    • Install the new switch and reconnect the wiring harness.
    • Reassemble the steering column cover.
Step 3: Test the Wiper Motor and Relay
  1. If the switch is functioning correctly, locate the wiper relay in the fuse box.
  2. Remove the relay and inspect for any signs of damage or overheating.
  3. Test the relay using a multimeter for continuity across the terminals. Replace if defective.
  4. Reinstall the relay or install a new one.
  5. Check the wiper motor by connecting it directly to the battery to see if it operates. If not, replace the wiper motor.
Step 4: Reconnect the Battery
  1. Once all repairs are complete, reconnect the negative battery terminal.
  2. Start the vehicle and test the wipers by turning them on and off to ensure they function correctly.
Step 5: Final Check
  • Run the windshield wipers through all settings (off, intermittent, low, high) to ensure they respond correctly.
  • Verify that the wipers stop when turned off and do not continue to run.
Conclusion

If after following these steps the windshield wipers still do not function correctly, further investigation into the vehicle’s Body Control Module (BCM) or additional wiring issues may be necessary. Consider consulting with a professional technician if the problem persists.
