Hello there. Just this july my brother's Renault RX4 has a problem with his car's A/C. It does not work and according to him the dash is working fine but there's no cold air. in addition, the compressor won't cut in upon the pressure is low and even if re-gas it won't work reset. He relay his problem to me and hopefully, he'll gonna find a solution for it. I decided to post this just to share and hopefully, one here knows about this issue and would probably help my bro.....hope to find replies from you guys soon. than you...!
