Car Model and Year

  1. Hey there, I'm new here. Last year I inherited a 1999 Deville with only 23,000 miles on the clock. Although many of its 21 year old features are still working a few of them are not. Case in point my A/C. Now I've tried everything, no ACM codes in diagnostics modes, no clutch click when jumping the relay, and I was going to try the voltage at the clutch but I can't seem to find where the harness plugs into it. It definitely has refrigerant, but I'm about a pound shy since I can't get the clutch to engage to suck the rest of it in.
  2. 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.
