You replaced the harness, not the switch? When my DIC was out and my HVAC quit doing what it was supposed to, it was the ignition switch. The contacts inside the switch build up carbon; its a pain in the ass, but you can take the switch apart and clean the contacts instead of buying a new one. Theres a write up if you do a search.

Yes, I replaced the switch harness as at one end there is the switch and the other is the harness that plugs into the cars harness. I ended up taking the car into a good electrical shop. They found a corroded wire under the hood where the wire bundle passes through the firewall. All is good now.
