B6 A4 hazard switch not working

[dagwood15t]

Hi im new to this forum and I have a 2004 a4 quattro 3.0 manual 6 speed
My problem is the hazard switch doesn't seem to work, it lights up with all the interior lights, but when pushed hazards don't come on
Blinkers and the alarm work just fine and they flash with the alarm. I have 2 switches and neither one work
is there a fuse or relay somewhere that could be bad i need to replace
any help would be great

The hazards are powered from the Central Electric Control Module under the driver's side dash. The switch activates the hazard flasher function. Either the switch is not fully connected to the CECM, or the CECM may be defective. The switch lighting and the switch electrical function are separate.

Ok so I checked the plug at the back of the hazard switch and get 12v but as soon as I unplugged the harness from cecm no power so I believe my wire are all good from cecm to switch so how do I test the cecm?
