2006 Chevy 3500 Duramax A/C Problem

[frogjaw]

The a/c control panel is not indicating anything. No power, no lights, nothing coming from it at all. I checked power going to the fan and it has power but fan will not turn on until I ground the hot wire. I replaced the panel earlier today but it did not help. Same problem, no power still. Does anyone have any ideas on what could be wrong or how to fix it??

start at the fuse box to see if the appropriate fuse isn't blown, owners manual lists them. From there trace the circuit for a break.
