Quick question. When the engine temp reaches designated value from PCM, should both fans turn on? Only one fan is turning on. Understanding that the second fan turns on when AC is on, but what about when AC is off - should second fan turn on low speed at least? Just want to make sure everything is working as it should. Also, set up is an LS1 fan and '02 truck PCM. Thanks as usual.

normal, mine did the same
Our fan harness works like this; When the pcm reaches the turn on value and the a/c clutch is not engaged on fan will be on LOW. When the a/c clutch is engaged and the pcm has not reached the turn on value one fan will be on HIGH. When the pcm reaches the turn on value and the a/c clutch is engaged both fans will be on HIGH.
Hope this helps. It sounds like everything is working great for you
Let me know if you need anything else.
