OK, I checked HPTuners and no a/c request when I turned the AC on via the Vintage air switch,
. However, I did verify that the compressor clutch is receiving power when I turn the system on.
My setup:
OPERATING SYSTEM:
12587811
AC HARDWARE SETTINGS:
Recirculation fitted:
#2 fan
Type Fitted:
Serial
Does this look correct? It's what was in the factory tune when I first read the computer. I think at this point, I may need to wait until the truck running before I can check out the operation of the entire system.
