Intercooler fan not working

[Pizzarolls4]

So I already had the intercooler fan wired up and it was working with key fan would come on. Yesterday I wired the taillights and the mirrors in that DF provides. I had the hazard button from the donor plugged in with the key on last night I pushed the hazard button and no hazards come on and now my fan has quit? I pulled every fuse one by one in the fuse box and none are broken any ideas what could have happened?
My harness is done by DF

The hazard button on my donor wore out... apparently it is cheaply made, as other cobalts owners have had this issue too.
When you wired your lights, did you disconnect electrical connectors or grounds? Sometimes they just need to be reseated.
Just a guess. I use a meter to test fuses, as it doesn't require pulling the fuses. You can also turn the key on, and check that 12V is getting to the fuse.

I recall now that u say something it being broken when I got my daily cobalt maybe I'll give it a shot replacing it.
I didn't disconnect anything other then just removing the negative off the battery.
Ill go through and double check the fuses that's good info u linked electrical isn't my strong point nor is understanding a multimeter.
Something that slightly confuses me maybe u can answer is there's a bundle of wires and is labeled "hazzard" why is there a connector for the stock button if there's a wire to the side? Is it for the button panel DF sells?

I did my own wiring harness, and am not familiar with the labels with the DF modified harness. DF does have a new hazard button on thier button panel... so you shouldn't need to use the stock hazard button. Hopefully someone familiar with the DF harness will respond.
