The dealerships thought it was the amp. Someone mentioned the replacement of the amp would not affect the CA. I thought I saw that someone switch their door handles, and that resolve the issues they had with all of the above. I had already replaced the battery, at the dealership, and they had quoted $1300 for the amp. They are not indicating that they’re not sure that’s the culprit. Can’t find the thread on doorhandles, so if anyone has seen that would you please send it to me, or any other thoughts. Greatly appreciate your insight.
