When the ventilation system on 2005-2010 Jeep Grand Cherokees and Commander stops blending the temperature correctly, the problem may be a broken actuator arm or blend door shaft in the air distribution box. This can happen when debris prevents the blend door from moving and breaks along the shaft.
Replacing the air box is an expensive and time-consuming job. The part alone is several hundred dollars, and also requires removing the entire dashboard to replace it.
Depending on whether a vehicle is equipped with a single-zone or dual-zone climate system and where the breakage occurs, Dorman offers OE FIX solutions that allow you to repair a broken actuator arm or blend door shaft without removing the dashboard or air box.
This video shows you how to repair either a single-zone or dual-zone system when the actuator arm has broken using Dorman part number 604-387, or when the blend door shaft has broken using Dorman part number 604-388. The video also demonstrates how to repair a broken blend door shaft on a single-zone system using Dorman’s blend door actuator relocation kit, part number 604-386.

Does this also work for a 2010 Jeep Liberty? I’m fairly certain this is the same issue.

What about jeeps 2011-up
Not sure why they are showing a product that is not available anywhere?
Nice Video! Just one question, what size torx bit is required? Also, while you showed how to perform relocation procedure, you did it on the bench and not in the vehicle as most of us would need to. Maybe redo the video? And more importantly, what is the part number and link for these kits???
I broke the shaft on the passenger side while replacing the heater core,fix one thing break more things , it's just the way she goes
