Help With AC And Outside Temperature Issue by Kaspar0v(m): 3:03pm On Feb 10, 2022
Anytime my outside temperature displays "--" AC doesn't chill. I noticed this few days ago. I initially thought it was AC issue.

what can i do?

It says 88F right now and AC is working.

but sometimes, I dont know what causes it to display two hyphens. And AC doesn't work.

The temperature sensor is either failing or there is a broken wire connection. It is located behind the front bumper. This has nothing to do with the AC.

Ambient temperature sensor at the front bumper is faulty. Ac system need the sensor signal to determine the outside temperature so as to know the level to set the coldness of ac inside the cabin.

Thanks boss.

I am surprised others say they are not related. When am driving the sensor goes off and AC stops cooling, sensor comes on and AC continues to cool. They are definitely related.

Wen it comes to modern vehicle, everything is interconnected that is why even as a simple as faulty abs sensor can cause your big wahala for your transmissions .

Mine has something similar.. when the outside temperature becomes 97F the AC will not work and car engine overheats. But later discovered the radiator fan was not picking up when the temperature is high.. it’s all fixed now

That's how it should work but my car (09 Camry) sometimes it will chill then stop chilling for like 5-7 mins until the entire cabin is hot and stifling then come back on again. The interval is too long in my opinion..
What could be the cause?
