Rich Posted July 23, 2014 Report Share Posted July 23, 2014 I had this issue twice in the past six weeks with my 1997 Eldorado, both times on rather hot sunny days. While driving with the A/C on, the cold air stopped coming out of the A/C vents. As you can imagine, with the hot outside temp and the sunload, the cabin became quite hot within a minute or so. I fiddled with the HVAC controls and the problem corrected itself. Notably, when the cold air stopped coming from the vents, cold air was still being produced as I could feel a slight cold airflow from the side of the console where the carpeting is loose. The compressor was replaced three years ago and the blend door actuator was replaced about four years ago. Just as a test, I just set the temperature to 60 and the A/C works fine. I then set it to the highest setting (90?) and immediately got heat. Seems to be fine now. The only codes that are set are: PCM P0325H; ACM B1313H; PZM B0533H; PZM B1971H; PZM B1983H. The only one that seems to have any relevance is the B1313 fault code, but I'm not really sure. As I said, the problem seems to have corrected itself and all the codes are "History" codes. Has anyone else experienced similar events? BTW, the Eldorado has about 135,000 miles, all of which were put on by me. As always, thanks for your opinions and advice.
