No radio after SAM replacement

So my front right turn signal got stuck on
Replaced SAM with exact same part number
Everything works except the radio doesn't come on, display is blank
Thoughts?

When I replaced my front SAM, I had to code the new SAM for a manual transmission car. You can read about my experience Post #21 of the thread I linked shows the adaptations in the SAM that can be coded. I don't see anything that indicates that the SAM needs to be coded in order for the audio system to work.

Although the problem may not be related to your SAM replacement, the fact that the radio stopped working right after you replaced the SAM strongly suggests that it is related. If it is SAM related, it could be that one of the connectors is not seated correctly or that you could have lost track of a connector during the replacement process. Another possibility is that one of the audio fuses blew. I suggest that you check the fuses and the connectors and see whether something is amiss.

Good luck. I know from experience that replacing the SAM is tedious.

It was the fuse, 64. My mind went straight to something difficult, but I can't complain about a simple fix.
Thanks!
From your other thread did you ever play with the rain sensor adaptation?
My auto wiper is hyper sensitive making that setting useless...
