Both front and rear windshield wipers and 12 volt accessory plug intermittently not working

Good morning,

All these are controlled by the Smart Junction Box or the BCM.

If the fuses are good, then most likely the SJB is the failure and needs to be replaced.

I attached the wiring diagrams for you to view to verify you checked the correct fuses.

The SJB is under the dash in the center.

Removal and Installation

1. CAUTION: Prior to removal of the SJB, it is necessary to upload module configuration information to a diagnostic tool. This information needs to be downloaded into the new module once installed.

Disconnect the battery.

2. Remove the floor console SJB cover.
3. Remove the transmission selector lever bezel from the floor console finish panel.
4. Apply the parking brake.
5. Remove the parking brake lever boot from the floor console finish panel.
6. Remove the floor console finish panel.
7. Remove the SJB screw.
8. Disconnect the electrical connectors and remove the SJB.
9. To install, reverse the removal procedure.
Configure the SJB. Refer to Information Bus (Module Communications Network).

Okay.

Keep is updated with your findings.

Is the BCM the same thing as the GEM module?

The SJB, BCM and BCM are the same. They have different names but function the same.

You were right, the BCM fixed it. Appreciate you.

You are welcome.

Always glad to help.
