The GMC Acadia's rear windshield wiper can be turned off using the wiper control switch located near the gear shifter. To deactivate the rear wiper:

1. Locate the rear wiper switch, which is typically a rectangular button with a wiper icon.

2. Press the top part of the switch to turn the wiper off.

If the wiper continues to operate after turning it off, there may be an issue with the switch or wiring. In this case:

1. Try disconnecting the battery for a few minutes to reset the system.

2. If the problem persists, check the fuse related to the rear wiper.

3. For ongoing issues, consult a GMC dealer or qualified mechanic.

Rear Wiper Operation

The rear wiper on the GMC Acadia has several functions:

  • Single wipe: Press and release the top of the switch quickly.
  • Continuous wipe: Press and hold the top of the switch.
  • Washer fluid: Press the bottom of the switch to spray washer fluid.

Intermittent Wipe

Some Acadia models may have an intermittent wipe feature:

  • Push and hold the rear wiper switch in the "on" position.
  • The wiper should activate every 5-7 seconds.

If this feature isn't working as expected, it could indicate a faulty switch or control module.

Troubleshooting

If you're experiencing issues with your rear wiper not turning off:

1. Check the wiper switch for proper operation.

2. Inspect the wiring for any visible damage.
