Hi

What with the recent hot weather i have notice that the Air Con on my ST works to start with and then it just stops working, when engine seems to get to normal temp(between about 5-10ish miles into journey).

I have had the System checked and was told it was full of gass, and that the condenser was not working - although it clearly works to a point as works initially when i set off!!

Any ideas, could a thermostat temp sensor cause this?
