Hi all,

Lately if my AC is working (either cooling or heating) for more than about 45 mins it reduces output. There is very little air flow out of any of the vents and if I manually increase the fan speed to the max setting there is still very little hot/cold air flow exiting any of the vents. If I press the ECON button on the climatronic pannel after about 1 minute the air flow rate increases as to the expected for the fan speed setting. If I run on ECON for around 20 mins and then swtich off ECON the AC will work fine again for approx 45 mins. I have had the system serviced in the past by a Skoda dealer so I brought it back to them and then couldnt find any faults on their equivalent of VCDS and the system was full of gas and lubricant so they advised me to replace the compressor as they felt it was the most likely cause.

Have these symptoms hapened to anybody else? Why if the compressor is faulty would it be able to cool/heat the air as normal for a set peroid of time?

I have searched online and cant find any issues the same as mine and I would rather not replace the compressor if its a simple fault elsewhere...

Thanks for reading,

Alan

I think when the cars interior temp is what has been set on the temp dial, the air flow slows just so keep it at temp.

The econ button only works the AC to the outside temp. ie will not reduce temp below outside temp.

Manually increasing the fan speed also switches off AC.

What you are doing is switching off AC then switching it back on causing it to work to cool down the interior again.

A faulty compressor, and the AC would not work at all.

It may be a faulty temp sensor /fan switch that thinks the AC has reached temp/speed so does not increase airflow.
