Title: what should i do about my a/c
Post by: 84chevyboy on September 12, 2009, 07:56:44 pm: ok i have been with this problem since i got my 84. well now my windows are tinted and i need to get tha a/c- heat working. well since saying that here tha problem. the air blows but its hot air. so i added some freon from autozone but to my luck it still blows hot,but when i but the lil gauge that comes with tha freon it said warning like something is wrong. but i didn't even put a whole can in. so could it be something more major or just the gauge is not reading right.

Post by: Irish_Alley on September 14, 2009, 01:48:05 am: well since there was nothing in the system you probably waisting money trying to put something in it since you probably have a leak. you probably need more that Freon in there also

Post by: micahadams on September 21, 2009, 10:36:28 pm: You should have the system evacuated, and leak checked. Then they can add oil, freon and even a dye. Its a good time to check and change the o rings and orifice cause it can get clogged.
