So you're thinking something with the tune? Or maybe it's just not reaching the parameters to turn the fans on?

 

I'm commanding the fan with the scan controls. it bypasses all peramiters in the file and just turns the crap on. Low setting is working (pin 42) and if I remove pin 33 from the pcm and supply a ground it works.

 

Could the ground circuit in the PCM be smoked, or do you think you have another issue?

 

I wasn't aware you could command the high setting? On EFI live you cannot. Highs only come on when the A/C compressor pressure reaches a certain parameter.

 

Could be. but seams odd. I'm using a factory harness, and the connectors didnt look like they have ever had a pin in stalled.

VCM controller allows you to activate multiple systems all in real time. Fat load it does me if HPTuners is the reason I cant control the high side.

 

When you turn your A/C on, do the highs come on?

 

Pretty sure I can turn my low and high speed on as I like using the temp settings, in EFILive.

 

I'm using the VCM to override the settings in the PCM. It should just turn on regardless of the settings or pressures.

 

Who made the harness you are using?

 

The general..... It's out of an 05.
