Waiting for module now. Second one to go bad since 2018. Dealer wants $864.00 for module and harness. Had right side replaced under warranty few years ago. You can replace these for about $300.00 including the harness BUT they still have to be programmed into your communication bus, and only G.M. has the proprietary software.I have getting the "Service Side detection system" in the information center, and can no longer turn it on or off in the menu settings. There is a previous thread that shows where the sensor/modules are located. Anybody have any DYI advice for fixing or turning it off? The lights in the mirror stay on all of the time. Or does someone know what might be involved having it fixed. The above previous post says the modules are $600.

Thanks in advance.
