Strange brake light issue

Hey guys first post here just been lurking.

I have searched and read and tried everything I can find. I feel like I understand the circuits but still cannot beat this problem.

The issue is that the brake lights do not work. I can measure 12v at the brake light pin in the bulb contact and I can jumper the bulb housing directly to the battery negative but it does not light.

I cannot understand why I am getting voltage everywhere I am supposed to but not getting light! I checked for shorts with my multimeter and could not find any that way.

One interesting find which may help diagnosis
Brakes lights won't come on but when I turn the hazards or turn signals on the bulb lights without being grounded (touching the bulb only to the socket without being in the housing). This doesn't seem right to me but maybe it is

Also fyi I put all new switches in including turn signal and the firewall to rear harness is. new.
