I need a hvac diagram for a 2016 pete 587

I need to replace either the floor vent door or actuator, being my floor vent quit blowing. I had it at the dealer cause they told me they'd be able to do it for 275 only to tell me the tech spent 3 hrs on it and would require another 9hr just for the diag being its located on the outside of the truck and he would have to drop the box. I figured before spending over 3 grand for them to replace an actuator id see if anyone can help with a diagram and do it myself.
Thank you.
