I have a 2009 Outlook and the vent control is not working. Air only comes from the main vents and will not switch to feet or defrost. I replaced the control module (found one without worn buttons!) but it didn't help. Any suggestions?
Do a search for "actuator" on this board and the other boards, especially the Traverse board. You will find that there are four of them and the post on the Traverse board has pictures showing their locations, what they do, and how to change them out.
Very common part that fails and prevents switching of the vents, switching between heat and cool, etc. Dealers charge over $300.00 to replace one. If you can DIY, the part is usually around $50.00 or less.
