Advice on A/C Problem and Service Bulletin

I had the Afterblow function enabled in my AC Control Module at the dealer. They knew exactly what it was when I asked for it then they said they checked the functionality after they made the change.

I've tried twice to get it to work but it doesn't come on. Here's what I know:

1. AC must have been on for at least 10 minutes
2. if you turn on the vehicle before the 10 minutes the system will reset itself
3. It must be 70d or higher outside temp

I've had all of that and nothing. I turn off the AC before I turn off the truck. Do you have to leave the AC on? I'll try that and if it doesn't work it looks like I'm back to the dealer - which I hate.

Dealer verified right in front of me that the afterblow is on. I saw the * myself on the Tech II. But it has never gone on so far. I keep testing it though. I feel like I keep checking my trap to see if the rabbit has tripped it!
