Hey Crusty.
It looks like you are correct. My auxiliary fan runs when the test is performed. ( Door Test also)
As it appears the main fan clutch was not working. We replace the fan clutch on the main fan, the engine fan. The Clutch was not operating the fan at a higher speed. It was just running with the engine speed.
The issue is that the dealer that a was dealing with they diagnosed the whole AC issues as a leak. I'm in the refrigeration service industry and i know that i did not have a leak on the AC System. One was because when i would drive the AC would work fine. When i would stop that's when it would kick OFF.
Even though i had told them that appears to be some king of an issue on the fans. Due to the condenser not cooling down. ( Fan Issues).
At the time i was not sure when the primary Fan (Engine Fan & Clutch) or the auxiliary fan were supposed to come on.
The main fan and the clutch seemed to be a very interesting setup and design. Also there is not much talk about them. Special on this vehicle. as far as i can tell.
And again the auxiliary fan seems to come on as needed from the main ecu im assuming.
After replacing the main Fan Clutch seems that all my issues have been resolved.
It is very interesting that there is no fault codes for the clutch on the main Fan.
A local mechanic some how had another vehicle in the shop same one 5.6 engine. As we were trying to diagnose my issue with his tool, he noticed that the other Vans main fan was moving much more air through it and running much faster.
That promoted us to focus on the Fan clutch. Which was the correct issue. Even though originally we were focusing on the small fan the auxiliary. But we could not find anything wrong with it.
We had looked at every HVAC diagram at the vehicle.
It does not seem to have much information on the clutch fan. It seems to be a hidden issues.
I want to thank you for the reply, you have the correct answers on this topic.
