Hello, I have a battery drain problem with my Civic FG4. When I'm parked, it drains the battery. I've even checked the stereo and can't find the fault. Has this happened to anyone else?

 

If your door lock works with the fob and all the windows roll up and down just fine and there's no motor that's shorted or making noises like it's ready to fry up. Try pulling the fuse for the Bluetooth. Make sure the car is fully charged up and then see if it dies in the morning. The Bluetooth module could be an issue from what I've seen from parasitic drains when other door locks window motors are solid. And that's if everything's stock like you don't have aftermarket amp or sub or something tapped into you're wire harness

 

Welcome. I have not had that problem.
