    Re: HVAC Control Module

    #10 is the programmer or control module as you call it.

    According to the 2002 Eldorado Service Manual I have (eSI), the HVAC Control Module is the HVAC panel directly below the radio controls.

    You might be dealing with a terminology conflict between GM/Cadillac and potentially incorrect aftermarket information suppliers OR, even worse, generic shop/street terminology.

    I would be willing to scan and post images of the applicable eSI pages. Within reasonable limits.

    The link above does list #12 as a "controller". Now I'm not sure what the difference is and which one the OP needs.

    The programmer obviously is involved with vacuum and mode doors. The controller may control fan speed?
