The A/C in my Megane 3 cc no longer blows cold air. I had it taken for a regas, but even after the regas it does not blow cold air. No leaks were found either. The a/c button is illuminated when engaged. I connected to the car with an OBD2 scanner, and it gave me the following error code: P0530(17) - AC refrigerant pressure sensor - circuit malfunction. Any idea what this could be and how to solve it?
