Ok, heres the deal. My 98 Sable has been blowing warm air out of the A/C. When I first got the car last August, it didn't do this. Now, I checked the level of R134a and its a little high. So, I figured this wasn't a problem. I also checked everything that was mentioned in detroitravers post about her air blowing hot air. Everything looks fine. All the hoses are connected, the door opens properly, and the RPM's drop a bit when I turn the air on. But for some reason its still blows warm air. Does anyone have any idea what could be causing this problem? Or should I just take it into the shop and have a professional look at it? Any input you could give me would be great!
