Khaki Nitro Nut
See this thread for a Vid. It's not complete but maybe you can find what you need.It’s got me stumped, I took the actuator off and had someone move the blend door by hand and you can see and hear it rotate from the other side of the hvac box. Taking the dash off the see what’s going on in the box. I have taken all the bolts off from what I’ve read and seen. I heard of a couple people having trouble with what seems to be something holding the center of the dash together. Does anyone know if there is bolts under the vent guard where the wipers are, allowing access to these bolts?
There is also a good write up on Lost for a KK, in the tech section.
