- this video shows the location and workings of the hot cold air selector actuator and heater core coolant valve on a 2012 volvo VNL with a d13 engine. it's probably the same on the Cummins engine volvo
what operated the vents. like when you switch the defroster on and back to blowing in your face? seems like mine goes out after a while
I drive a 2021 vnl760. I can’t control the a/c. It’s either all cold or all heat.
Same with my 2019 , did you find out what is wrong ??
@@Pelinas Nope. I still drive the truck because it run great otherwise. I had a 2010 Prostar a/c problem for 3 years. Another truck driver at a truck stop, told me how to fix the problem. I hoping that happen again.
This is a very bad design from a mechanical stand point which causes endless ac issues.
..that dosen't go up , it goes back in to the engine , it also have an arrow pointing down for the flow of coolant (outlet coolant core valve) . .. good vid anyway . 👌
