So, my car battery constantly keeps draining, even though my battery and alternator are fine. My locks, radio, and wipers keep acting weird. Me and my grandpa took out my BCM, it had corrosion. We cleaned it up and put it back in my car. Yet I'm still having the same problem.

Hi,

This could be the result of several things. Do me a favor. Read through this link and check what is suggested:

If it isn't anything obvious, make sure to follow the manual check at the end of the link. If you need help, let me know.

Take care and let me know what you find or if you have other questions. Also, let me know how much time is needed for the battery to drain.
