Hi. Make sure you checked for power on the purple wire at the switch with the AC ON. Next if you still have no power there you need to check fuse 5 (15amp) to make sure it has power on both sides of the fuse.
If that fuse is good you are going to have to access the atc unit and make sure you have power leaving the atc on the purple wire going to the cycling switch. Please do these checks and let me know. Thanks.
