Howdy from Tennessee, I'm Chris aka Moose. Who am I helping today? I'm glad you've come here to get help. I will do my best to get the answer you are looking for. I help many customers, so sometimes my replies are delayed, I will respond once available. I try to be online at 1-5 pm and 10 pm-5 am every day. This is only affecting both rear passenger doors, not the front doors or the liftgate, is that correct?

The lift gate keeps locking and unlocking after I turn car off, draining my battery.

Thanks, \*\*\*\*\* \*\*\*\*\* is going to be a faulty BCM body control module. It controls the electrical signal to the liftgate latch. When replacing the BCM a DRB scan tool is needed for programming. Thank you for seeking us for help, I hope I provided what was needed. Press reply if you need to follow up. If you liked my answer please let me know so I can mark your question complete. Moose

Checking in with you. Please let me know if you liked my answer, or need more help.

Well I ordered the part..I wish I knew how to put it in myself. But I made an appointment
Automotive Expert
Keep in touch as needed. This module requires programming using a dealer equivalent scan tool. If you have one I can show you how to replace the BCM.

Thank you so much for your help! I made an appointment, and I am waiting on the part. so I'll only be paying for labor costs. I hope that fixes my issues.

You are welcome.
