My 97 Aurora's ac did not work when I bought the car, which was fine but I figured charging it would be a cheap try to make it work. Well it does not work lol, I think there maybe a leak but I am not concerned about that because I can just roll down the windows. The concern I have is after a while its making a noise when I am idled or moving slowly. I am not sure if it is making the noise while going faster too but as of now I have not heard it. I am just wondering if it could cause any further problems, if possible I can get a sound file of the noise for reference. I was thinking about getting a shorter belt and skipping the ac completely too. Also anyone know of a cheap if not free way to fix a slowly leaking tire? not sure if its the seal or a hole.
