Hello -

Thanks for the info.......

If you don't mind..... Please tell me exactly what you vehicle is doing.....I am not saying it isn't a sensor... But lets start from what it is doing and take it from there so I don't lead you astray.

Also, Please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.

Thanks for the info. . .. . .. . ...

I hope you can see the pic. . .. . .actually there are 5 sensors. . .. . .in car temp sensor, outside temp sensor, solar sensor, A/C high side temp sensor, and the A/C low side temp sensor.

They all feed into the Heater/A/C programmer. . .. . ..

Again, please tell me exactly what the vehicle is doing.

Also please do this test and tell me the codes. . .. . .. . ...beside going to AZ or OR and get those codes.

ACP SELF-DIAGNOSTICS
NOTE: Operating vehicle in SERVICE MODE for extended time periods without engine running will drain battery, possibly causing system to give false diagnostic information. If vehicle is to be operated in SERVICE MODE for more than 30 minutes, connect charger to battery.
Entering SERVICE MODE
1. To enter SERVICE MODE and self-diagnostics, turn ignition on with engine off. Simultaneously touch OFF and WARM buttons on Climate Control Center (CCC). See Fig. 2 .
2. Hold buttons until a segment check is displayed on Instrument Panel Cluster (IPC). This should take about 3 seconds. If any segments of IPC do not glow, replace display.
NOTE: In SERVICE MODE, PCM, ACP, IPC and Supplemental Inflatable Restraint (SIR) system can be tested. Only information relating to A/C diagnostics is given in this manual.

You have a high temp and a low temp sensor in the system. They are both the same parts, and replacing one does not mean you need to replace the other. They(GM) must have discontinued them within the past couple months. I don't have a part number for the sensor, or the harness connector with leads. The latter is on my bench at work.
