Well after replacing a dryer and compressor, I went to a shop to have my system evacuated and charged. The system appeared to work but I had to keep the car on constant "LO" to get any results. The pressure on the climate control was running 5-9. On the way to work, I turned the system on and the pressure shot up to 25 and then down to 14 and cooling stopped. Well now the car is not cooling, I have checked for leaks, none that I can see, the compressor is still running, here are my results from my climate control, first one standing still the other with the car in operation. There was a fault code of 1232, for the pressure switch, I reset which has not come back on. Is all this a result of the pressure switch? I have tapped on top of the duo s but that has not helped. Thanks for any inputs!

Rebuilt Denso from Company with very good track record. Are you thinking the compressor is not building the proper pressure?

5-9 bars pressure on working compressor is low.
Take the car back to the shop.
