    its something on those circuits. good job, just gotta narrow it down now .

    I'd venture a guess at the Air pump. I've had my fans working and running correctly with enabled and working EGR, EVAP, and AC. but I've never had an air pump. so that may be a good place to look.

    this is very late post but if you have any mechanical ability and a little common sense you can get there with lextech's layout. He is a intelligent individual and has my full support with the work he has accomplished

    If you read the whole thread, you would see that I'm using Lextech's schematic or layout...Vortec 4.3 V6 BlackBox to 0411 PCM 4.3 V6. He has my full support also...

    I re-installed all the A/C pins to the PCM one by one and everything works....Fan turns ON/OFF like it's suppose to!
