Had to remove Hvac assembly to replace lower case. Disconnected

Customer Question

Had to remove Hvac assembly to replace lower case. Disconnected IP harnesses, air bags, radio, etc. I only disconnected the main single plug on the back of the BCM. Now with everything together the remote access does not work. The dome lamps do not turn off unless defeat button is pressed and radio turns off with key off inside of when drivers door is open....does the BCM need a relearn?
JA: Sometimes things that you think will be really complicated end up being easy to fix with GM. The GM Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: Yes but I work at a GM dealership also
JA: Great! What have you tried so far?
Customer: Making sure every harness was plugged in
JA: Is there anything else the GM Mechanic should be aware of about your GM?
Customer: No pretty much explained
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the GM Mechanic about your situation and then connect you two.
