I wanted to send an update. I got home today and the locks still where not locking. So I got to the BCM played with the wires and no luck. So then I removed the BCM. I looked over the board it is different then the older ones on the LS1 forum pics. The 08 board is a lot tighter. So I did not feel comfortable doing any soldering. I put the BCM back together and plugged it back in. After getting the battery connected again the locks are back to working.
Just a FYI the night before I did disconnect the battery for a long time and that did not do anything. So I know that did not help in the fix today.
Not sure it could be the board or maybe it is was a bad connection on the plug or terminal. When I unplugged it and plugged it back in it cleaned the connection.
If the locks go back not work working again then I know it is the board. I will post up.
