no voltage at g395 connector

[audi_wala]

Hi All,

I recently purchased audi A4 2008. I found that Ac of car is not working. When diagnosed by carista module, I found it is showing 00457 and 0256 error codes. Please find my attached screen shot results. After doing some research i found that this fault is related to g395 sensor. I first replaced the sensor but it dint resolve the problem.

I then checked the voltage on g395 connector. I found voltage between ground and 2nd pin is fluctuating between 9.5 and 10 volts. However there is no voltage between pin 1 and 3, which i believe is ground and power.

Can anyone guide me what i need to check further, where can i find the fuse where these connection are going.
