    Wanted to turn my truck ac on and noticed that in sleeper everything works ok but in cab no air is blowing and nothing works.
    Also module is not illuminated as rest of dash knobs.
    Checked the fuses , everything looks ok . Just wonder is there somewhere another set of fuses die that Control module or i need new module? Also , Could it be a blower motor , but I doubt that is the problem as there is no power to module. Any suggestion?

    Maybe this:

    Also:

    You have 2 fuse boxes for rear a/c.

    The first is in the storage on the driver side that's the most common.

    The second if you have no idle is under the bed on passenger side under a metal cover that's held in with a screw.

    Also check fuses in front of passenger seat on top of dash the cover just lifts off.
