Monaco dash air problems

[tommonaco05]

Hello everyone and thanks for your help.
I am working on a 2001 Monaco diplomat on a dash air. Air is coming out of the defrost and I am not able to change it. I did some testing and all of the vacuum actuaros are good the vacuum pump is not Turing on. If I provide power to the pump directly everything works fine. Does anyone have a wire diagram or where is the vacuum pump gets the power from?
All circuits beakers and fusses are good.

Welcome to iRV2

I'm sorry I can't provide any exact location for the power supply on your Monaco , but I can say that on my coach with a similar Evans Tempcon , vacuum controlled dash air the pump is powered direct from my ignition and will run even when the dash control is in the off position .
The pump although supplied by Evans to the coach builder isn't shown in their wiring schematics , so it's up to the coach builder to figure out how to power it.
Here's some info on Evans systems.
