About 3 months ago my bluetooth started "freaking out". For about 3 days after turning off the car, I would get a crazy loud crackling sound through my speakers from the bluetooth. Then nothing. Bluetooth died, couldn't find it with my phone, connect to it or anything. The next week, my battery started dying; it was the end of December and temps were well below 0F; so I bought a new battery figuring that was the issue. After that I had noticed weak starts if the vehicle was unused for more than a day. Then a month ago after my first day off this season, my battery was dead. So I changed my alternator, Still the battery drains when it is not running. While the vehicle is running it sits at 13.64V. Turned off with no electronics on it is at 11.7V and after 8 hours turned off it is at 11.2V.

It just dawned on me the other night, the connection between the Bluetooth and the battery problems. Should I just pull the fuse? If so which one? or do I need to dig deeper to find the BT module?

I don't have to have bluetooth so if I remove the module I am ok with that.

 

Not really sure. If you can find the fuse and pull it you could then check your battery drain and see if that was the issue.
