Porsche 944 Aircon electrical circuit check & bypass

[@Seagrams]

Huge thanks for the video. I was able to confirm my ac system was working by giving 12v to pin 8 as you did. That narrows it down to the climate control unit or ac switch. I will try to diagnose further

I wish I have all the time & a camera man so I can show everything properly very hard.
I will do more diagnostics for old 944 928 etc
