2010 987.2 here.

Noticed that the climate controls stopped working. There was a weird smell coming out of the vent.

None of the buttons work except for the fan speed and the windshield defroster (can see the orange light).

Last time I was able to use the temperature control on "auto" it was set to 20c and is now set there. I can toggle the fan speed up until half way.

Heated seats no longer work.

Hoping for some suggestions.
