Need help with a ground issue

[rolfsent]

I have a 1999 Denali and my radio, blower and left turn signal anne do not come on. I've narrowed it down to a ground issue and started checking grounds in the engine bay and I couldn't find anything. Where are these grounded?

I would look at your body control module.

n the center console, but the BCM is buried deep under wires.
