Climate Control Console/Vehicle ID Center no longer work? Anybody help?

Hi there, I have a 94 GC Limited 4.0L I6. A few months ago, my climate control center along with my vehicle identification center stopped working. I have no control over the heat/AC and there is a constant warm air flow coming from the defrost. Also, the overhead info unit (that shows direction and outside temp) stopped working at the same time. It's not THAT big of a deal to me since I've lived with it since they went out, but I would love to figure out why they stopped and what I could do to remedy this!! Please help!!

edit: There display no longer works on the climate control panel or the vehicle ID center and the overhead unit shows direction, but not temp.

If they both went out simultaneously, logic would suggest a power/ground problem, which is easy enough to check for. First stop would be to check fuse 17 for the ATC (climate control unit). I don't think that a fuse is an issue for the VIC because it shares two fuses with the overhead console, and that's getting power, but check fuses 8 and 19 anyway.

The reason you're not seeing the temp on the overhead display is that the feed from the ambient temp sensor on the front of the Jeep is sent first to the ATC and then from there on to the overhead console via the CCD bus. If the ATC is not getting power then you won't get a temp readout on the console.

I checked every single fuse in both fuse boxes and none of them were bad.

Then it's time to break out the multimeter and start checking for volts and good grounds at the harness connectors on the backs of the modules.
