Thanks for the links, however they show the server is down at the moment.

For a test I unplugged the auxiliary water pump. Well I must have unplugged the line going to the mono valve as I unleashed the fires of hell heat in the vehicle. So now I have a/c coming from the center vents and lead melting heat coming from the defrost and the small side vents. I will reconnect the line that I disconnected and will see what happens.

I will test the gang of 7 this weekend and see what works and what doesn’t.

Thanks again for the assistance.
