Does anybody know if the BCM gas anything to do with the speakers. My left front door speaker and rear door speakers have stopped working. it's the stock stereo. sometimes the left front door speaker and the left rear speakers work, then they stop. The right front door snd the front tweeters do work. HELP.
Thanks Steve

 

I would start with the basics on this one. Stock speakers are crappy, and could have just gone. Also it could be the wiring harness at the door where it flexes.
Pull your drivers door panel, and grab a spare speaker you know works,and test the wire at the stock speaker.....then work back to the radio.

Not a pro answer, but my two cents.
Good luck.

 

The BCM only supplies a digital signal to the radio to start and stop the turn signal and other chimes.

You have a radio problem.
