The new Cascadia

I think this is what they refer to as 2020 and up models.
Here are some picstures.

 

If this is a lease neauville than it was rebuilt?

And Japanese AC compressor?

 

I think the compressor says it's filled with 134a?

I do not understand the AC max button on the dask. It seems to have 3 modes off, green light, or blue light.
And the fan is very restricted flow I feel. Cooling starts to lag a bit when ambient air is around 80, does not cool cab well.

 

Has anybody else noticed in the new style Cascadia that it's always kind of hot inside truck??
I can feel heat radiating from the truck, even when it's 50 degrees out I run the AC with Windows shut. I do not like Windows open in new type trucks no air flows through the truck and it's just noisy, or dead quit.
When it's chili outside and I just use the fresh air vent setting it blows warm no matter what.
Hats off to the great engineering team at Freightliner Benz.

 

I use green was not sure what blue was. Seemed Max AC mode ices up when I've tried it.
