Answer
Hi Mike,
The power for the ATC comes from the body control module which in turn gets that power from the ignition switch. The ATC control panel should show a light all the time and that comes from the only fuse that is involved #14. So either the bcm is not getting voltage from the ignition switch (check the pink/white wire on pin 5 of the bcm #2 plug (green interior), OR the bcm is not passing that voltage along to the ATC (gray/pink wire at pin 10 of bcm #4 plug (gray interior)  or the wire is not reaching the ATC on pin 5 of the ATC's black plug. Finally if you do have voltage when the key is in the run position then the black/orange ATC ground wire from pin 11 of the same plug is not being grounded at the ground point under the dash to the right of the center stack. If all that checks out then perhaps the ATC unit itself has failed.
Sorry for the delay in responding but I just found your question in the 'question pool' to which Kevin had referred it.
Please read the PS below.
Thanks,
