Check the SIR fuse in the underhood fuse block make sure its not blown, if its ok replace the rear view mirror, looking at the diagnostic if the screen is blank and the connections at the mirror are good replace the rear view mirror. Post back with what you find.

I had the same problem on my 03 Sierra. Talked to a GM mechanic friend and he told me to check the wire harness under the pass. Seat for knicks or a cur wire from the pass seat being slid forward and back. Sounds crazy but low and behold I found a cut wire in that harness, spliced it and it fixed the compass/ temp readout in the rearview mirror. It's worth a look. Good luck
