I have created a tool in modelbuilder. I use the make feature layer tool to create my layer. I right click on the layer and select a symbology. I run my tool and I can see that my symbology is applied on my layer correctly, when using add to display.

However the resulting kmz does not contain the symbology of the layer. Does anybody know how I can involve the symbology in my kmz ?

part of my tool is shown in the following image : (Arcgis 10.2.2)
