Thanks so much for this. My heater fan was faltering when I most need the Airco to work in the European heatwave of 2022. I had a feeling it might be a loose connection because it would come alive when banging on the dashboard or hitting a bump in the road.

Followed these instructions and found a break in the connection between wire and connector in one of the wires of the adaptor. How this came to be, is a mystery but I managed to open the little female metal pin connector at the end of the wire, reattach it with fiddling and some tape en reassembled the thing. Works perfect for now. Must say the job was not too comfortable due to the strange twisting weird posture you need to reach the %#*@ thing!
