Just wondering what happened to my Sentra's Air-Con. I noticed that when I started my car there's a loud squeaking sound when the air-con was turned on, when I switched it off it disappeared. So what I did was to just turn it on and just stated driving. while driving the sound disappeared for a good 10 seconds then it came back. During that time I noticed that there was a white smoke on the right hand side of my hood (near the side where the freon tank is located) I guess that was not smoke but the freon itself. then I noticed that the sound dissapeared and my air-con tured into just a regular blower. Can someone help me identify what was the problem, I dont want to just rely to mechanics because I know that they will just replace everything for the sake of getting money from you. Also any trusted mechanic near malabon/monumento area? My car is an old 96 Nissan Sentra Series 2 Lec 1.3
Thanks in advance for the help.
