Hi guys, reelal here and I have a question, I've called myself looking, a lot, but is the interior fuse panel and the BCM the same piece of gear and is there more on the back side of the BCM that I can't see. I've already learned a considerable amount from you guys thank you. by the way, I don't see but one relay on the front of this BCM and the OM shows three. That's the reason for my question.

My owners manual shows 3 relay positions. The diagram shows 1 with solid line and the other 2 with dotted lines. Even the description shows one of those spots as being "Empty".

Yes. I would say only 1 spot is used on your's.

Maybe another year, model or different equipped HHR gets that second relay.

 

Thanks Firemangeorge, my owners shows the fuse block but I believe it's upside down from the actual BCM in the car, maybe now I can trace the current flow. Thanks again.
