I have two questions and they may be related, but I'll pose the most important question first. A friend owns a 2006 Chevy Malibu. Recently the running lights began randomly turning on when the car was off. Sometimes they would turn off, otherwise they would stay on and drain the battery. The lights switch is in the off position, and the interior lights are off. Why are they turning on?
Second question, which may be connected. When driving and attempting to turn on the left (I think only left) blinker, the blinker stick (sorry, I'm not sure of the correct name) will not stay in the on position, and needs to be held in the on position for the blinker to work. Why is the blinker stick not staying in the on position?
I hope my questions are clear. I have done some research and found that this year Malibu is within the year groups that have electrical issues causing things like the running lights issue to happen. These issues seem to be traced back to the BCM. With that being said, are there other options for why the lights would turn on other than a faulty BCM? Or are these issues possibly due to poor connection issues?
If the BCM is the cause of the running lights issue, could it also be the cause of the blinker issue as well? I have done some research and it seems that the blinker issue could be caused by a separate issue, a faulty blinker switch.
I hope this makes sense and is the correct thought process to begin diagnosing the issue(s). Any help would be greatly appreciated. Thanks!
