Well I lost alot of my accessory systems. Pulled the fuse box apart and checked for power before and after the top portion of it to the systems that are out. The top part tested bad.

So my question is, does anyone know what the part # is for the top portion of the underhood fuse box?

2006 cobalt ls, 2.2L, automatic

 

I read that there is a relay also on the back of the BCM that comes loose and will cause the same problem.check it out before replacing the fuse box.
