dumb question but are you using the correct pins? 42 in one connector and 33 in the other?

 

Not dumb I had forgot all about it at first and was using pin 42 and 33 in the same side. now I have pin 42 in one connector and 33 in the other. I just tried using your settings with your hptuner version but still no go. You can turn the fans on manually with VCM controls right? I know I could with the 05's....

 

i dont know then. yes i can manually turn them on and off with the vcm controls. if you manually ground the pins do they come on? what harness are you using?

42 in the connector toward the engine and 33 in the one towards the fuse box right?

 

yep on the connectors, yep, if I ground the pin manually it works. it has to be in the PCM itself. The harness is a factory harness out of an 05.

 

you don't have the low and high speed wires swapped do you?

 

swap the relays to make sure they are good also

 

nope, and nope. the fans function as they should if I manuelly ground pin 33. It has to be a program/OS/HPTuners problem...

 

well that sucks. maybe charlie or someone else will chime in. i didn't do anything special for my buddies truck. although his was an 04 like mine. maybe because its a os for a 2500.
