2000 Buick Century Q&A
2000 Buick Century Question: A/C failure due to defective Ambient Temperature Sensor?
Our Buick's A/C works intermittently. I had the system recharged to no avail. Then I noticed when it was failing, the ambient temp reading showed 22F. That would account for no cold air being produced. I found the sensor located in front of the radiator. Question: Is the false reading more likely due to the sensor or the computer? Anyone out there had this experience? - Balloon Chaser
The system should maintain the temp. you select no matter what ambient temp is! If you want to test the system /sensors it will need to be scanned for trouble codes. I assume it has digital/auto. climate control that is set to °F scale? Reason being that 22°C would be about right for ambient temp. (july) at your local, on average!-- I think. Either way, the scanner will tell the story. - pushrod
