@AndrewWinn: Yes, correct no air whatsoever comes out of the vents in the front of the cabin, so HVAC cabin blower not coming on. I have checked all the fuses, including the 50 AMP fuse and they are all good.

I did check the rear blower just now, and the rear blower did come on and air was blowing out of those 2 rear vents.

I let it run that way (with the engine running and the rear unit blowing to its max) to try to refill the A/C system with one of those cheap kits with a gauge on top of the can. As I was doing that, I noticed that the A/C compressor gets engaged off and on. It engages for about 10 seconds then off for, say 30 to 50 seconds, and then engages again for 10 seconds, and so on...

As it was doing that, I also saw that the Aux Fan was spinning now. That's a small win :-)

When you say "the scanner software should show if compressor is engaging", which scanner software are you referring to? INPA? I did not see anything about the compressor in the INPA screens. :-(

I did use INPA to command the blower to come on but it did NOT come on. So, I will go looking for the thread you mentioned about manually engaging it via the FSU connector.

BTW, I am not familiar with the term FSU, what does it mean?
[Edit] FSU = Final Stage Unit, I had heard about that, just not the acronym! :-). Also, found the thread for testing the connector. Gonna do that as soon as this darn storm passes.


Thanks!
