The bad news, The PCM still does not recognize the 12v A/C request!!! I could wire around that, But what I found out when I jumped the A/C Relay really made me upset......The Fans do not respond to A/C pressure, But they do to coolant temp.

The A/C head pressure is getting read by the PCM, Makes no since to me, I have sent this PCM off TWICE to fix this stuff to no avail. You would think having my PCM for 2 months total more than one of my issues could be resolved.
I will start a new thread on this, Maybe someone has some suggestions.
