Fresh air actuator location

[Waterloo]

From what I have read on this forum, it could be under the hood on the firewall. It would be nice to know for sure before I tear my bottom dash apart on the passenger side. Any help is greatly appreciated. Thanks in advance

The fresh air actuator is located under the hood. It is attached to the fresh air intake box. You will need to remove the cowl, the plastic piece that has the hood rubber bumper on it. It is just a few screws. If you are standing at the front of the truck it is attached on the right side of the box. It is a different actuator than the ones under the dash and in the sleeper. BUT! There is always fresh air blowing through, been trough this myself. You cannot shut off the air coming into the cab, been through this myself. Close the air vents on the dash or turn the temp control to heat if you are getting cold... It is Winter.

Side note, these under hood actuators rarely fail. The other ones, dash/sleeper, very common.
