Rear A/C is still ice cold, front A/C is room temp/ambient.
I have searched a handful of times and keep coming up with the same results. Sounds like I have a blend door issue.
What diagnostic tool can I purchase to diagnose this myself? I know some tools will actuate each blend door on command to verify if the actuators are working or not. Is there a budget tool that will do this?
Also, is there a write up/video on accessing and changing the actuators? I've seen them on the older trucks, but can't find anything on the 15+
Any information is appreciated.
