I have 2010 corolla that a/c stop working, not blowing cold air. first i hear a noise in the compressor so i added refrigerant 134 in the low pressure side but it won't suck so i assume that the compressor is not working there is a 12v supply to the compressor. This compressor is a clutchless design. So how to add oil on this compressors? Anybody has a suggestion?
