Aircon Problem

[colin1230_1]

Hi

 

I have Mk2 Galaxy the aircon is not getting cold vag .com came up with possible open circuit on Sunlight sensor g107, I removed the sensor from the dash & found that it was not connected, also I cannot find any wires in the area.  Will this prevent the aircon working entirely?

 

Does anyone know what the wires connect to at the other end so that I can trace back.

 

Thanks

Colin

No idea on the sunlight sensor, doubt its related though.

 

Any idea if theres still gas in the system - if not theres a pipe that goes between the engine and chassis which has a tendency to snap on certain models, Think its somewhere around where it exits through the undertray that it usually goes.

Thanks for your reply, I dont know if it has gas, have booked in for regas tomorrow, should the compressor still cut in if no gas? CC display is flashing on startup vag is showing pressure switch & sunlight sensor.

Pressure switch suggests low gas, usually stops the compressor from cutting in to prevent damage.

 

Sunlight sensor is only used to trim the outlet temperature when sunny.
