Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello I will help you with your question,
The ambient temp sensor is mounted behind the right turn signal as shown here >click<
Look for it and let me know if you can find it. If you can and it is intact I can help you replace it and test it.
What does the temp read? just lines?
If you short the connection together with a paperclip do you get any reading on the mirror? It should read very hot. If the engine was off for more than 2 hours and the engine temp is almost the same as the air temp the mirror should read real time
You tested the resistance of the sensor and got no reading as if the meter leads were not making contact? If so the sensor is open and needs to be replaced.
Let me know how I can help
You can force a temp reading by turning the key on and pressing the mode, front defrost and the rear defrost buttons at the same time
No, the sensor is plug and play. Do you have the manual AC controls?
OK, so that is the automatic system.
If the sensor read open with the ohmeter then I would replace it. Tose are only a few dollars.
Yes, I understand
