[QUOTE="MrMike2010, post: 1121852, member: 2509"] Sounds like a blend door actuator took a dump. With the key on engine off try switching the vent direction. The actuators in these trucks suck and tend to "get lost" and just click when they are told to switch a position. I'm not sure how difficult they are to change on a 6.7 but my 6.4 I was able to contort myself into an awkward position to change the one bad one out. If u still have a warranty left it should be covered. If not, find the one that clicks and replace. The actuators are fairly cheap. I think I picked up an actuator for like 20 bucks. [/QUOTE]
