Gremlins OR FSR?

[Bmwtvboy]

1. Was told my CCM on dash was toast. Bought another off ebay.
2. Hooked it up. Nothing, no lights, nothing.
3. Light test/current the 34,48, 3,fuses. Nothing. No current at fuse and no current at the power connection to the CCM.
4. Disconnect the new / used ebay unit and voila, Rear blower fan kicks on when ignition is in Key position 2. Fuses still show NO current.
5. Turn off key, rear fan goes off.
What is going on? Is this a FSR part? It was replaced with Behr about 6 years ago. I noticed issues with original CCM, blowing fuse/34,48, n only rising the fan motor in MAX, but still able to lower the fan . A/C worked fine, but only on 60 degrees/cold, any other temp/blew the fuses.
What should I do not to waste money throwing parts? Could it need a new FSR? That's cool. Is it a General Module? Can't figure out why not power to the fuses.
Thank you.
