no brights when lever pressed forward... lights shut off?

2008 SS... Ok if I pull lever back I have brights... and I let go I have my normal lights. I push lever forward for continious brights my parking lamps are the only thing on? I'm completely stumped! I even replaced stalk, same issue. I've searched high and low to find an answer I can't find squat.

Wow... 8 years since my last visit to site :eek:

If your flash to pass works(both hi beams), but when you switch to hi beams they don't, then you would think it's the multifunction switch....but is that what you already replaced?

If it is, then you either have a bad circuit(open) between the multifunction switch and the BCM, or a bad BCM....

ugh and I heard the BCM is expensive to fix. Good grief... yes I replaced the whole switch and it continues to still frustrate me :banghead:

You will need a schematic to check the circuits between the multifunction switch and the BCM......you don't want to put a BCM in for nothing....
