The Air Quality Sensor shouldn't keep the A/C from working, but the A/C Pressure/Temperature Sensor (G395) would. If you've already replaced that sensor, first I'll ask: What was the source of the replacement? If OEM, then I think you need to get a wiring diagram and check/verify all relevant wiring and connectors.

Problem sorted there was no power to either of the sensors, traced back to the fuse number 6 if I recall correctly. Thanks again for your input.
