Bcm Replacement


Recommended Posts

Posted

sorry for the last post. the dell "boat anchor" screwed the message and never completed the post.

has anyone had their BCM replaced? if so, what were the symptoms that prompted GM to replace it.

my sierra goes completely haywire(electrically) after extended periods in the sun.

thanks

Haven't had a BCM replaced but would think that multiple apparently unrelated electrical systems failing at the same time would point back to the BCM. For example if your horn, lights, radio, and windows all went weird at the same time.
