2004 GMC, electric fans won't come on

[Foose04]

After some searches, I found I need to download a beta? Where I get it or can someone please send it to [email protected]

I have electice fans and use the Blackbear harness, pins 42 and 33, but fans wont come on.

Thanks, Rob

email support at hptuners.com they will need your serial number. the engine portion of the fans should work. you need the beta for the a/c portion to work. but you will have to download a 05 tune and copy and paste the settings over.
