Electrical issues

[taxman]

My 2007 Tahoe LTZ has recently displayed odd electrical issues. About a month ago, driver side rear brake light was not functioning. Changed the bulb and still not working. Put the old bulb back in and next day it worked fine. A few days later, passenger side headlight and DRL not working. About 4 days after that, passenger side headlight working fine but drivers side headlight not working. Garage door opener does not work; not all of the keyless remote features work; driver side interior light does not illuminate when opening the door but it does work when you press the overhead button. Does this sound like the BCM is bad/going bad?

Thanks

Or possibly a short somewhere in the system

I would be checking all grounds and even load test your battery...

Start with the simple and free
