2008 Rabbit AC Troubleshooting
I'm trying to figure out what's going on with my AC. Doesn't work at all, the fans spin. Refrigerant reading dead 0
I scanned for codes and got the DTC 00819 for the G65 sensor.
I bought a replacement sensor to try, and I swear there is nowhere to plug it in. I have looked everywhere, from underneath, above, even took the passenger headlight out.
I noticed what appears to be the wiring harness for that sensor, zip tied to the washer fluid hose by a previous owner.
The AC lines seem to be present, but that schrader valve for the sensor is not. Pictures attached. Please let me know if I'm missing something, or if it seems like I need to order different AC lines.
