Help. Instrument Cluster and A/C lights not working

MustangLife said:

I just installed a aftermarket head unit in my car. And now the lights for the gauges and a/c arent working. I checked all 4 fuses dealing with the instrument cluster and found 1 blown. A 5 amp fuse. I changed that and that made the miles light and the lights at the bottom of the cluster start working. But still no guage or a/c lights. The big maxi fuse under the hood for the instrument cluster and pcm was ok too.

So anybody have any ideas. I was thinking maybe it had something to do with the illumination wires for the cd player. But the illumination on the cd player works fine.

Thanks in Advance
Josh
