I have been troubleshooting AC/Heater issues for a while. I took to a Porche/BMW/MB (in that order) garage and they could not figure it out. They tried switching out relay and that did not work, so they put in the old one. That is all they should have done. In doing that, it looks like my thermometer display broke. Has anyone seen this? See image.

It slowly cycles through several characters every several seconds. I am not sure what could have happened. Any ideas?
