Climate Control Issue

[Voice of Reason]

I'm having an issue with my climate control when it's in Auto mode and want to see if anyone else is experiencing this. For some reason it thinks my car is hotter inside than it really is and it wants to blast AC on the highest fan setting. It will sometimes calm down bust most of the time it's freezing me out. Just yesterday with outside temps of 65* and my window open when I hit Auto with the temp set to 72* it was full blast AC for no reason. It will even do this if I adjust the temp to 80*, the only way to stop it is max the temp high and then it switches over to extreme heat blast. Of course I can manually turn the fan down but it's a pet pieve of mine to have Auto climate in a car and not utilize it.

The software is up to date and the dealer didn't find an issue, it's sporatic but works incorrectly more than its correct. I suspect the temp sensor in the car is bad, does anyone know where that sensor is located? If it's burried deep in the dash I'll have to learn to live with this, I'm not having the dash taken out. But if it's more accessable I think I need to try something.

Not warm enough here yet to use the AC. But, what you describe is pretty much my experience with every car I've ever owned when using the 'auto' setting on the climate control. They generally just come on like the car is trying to achieve a hover and at some point in the way distant future, calm down.

The sensor is below the steering column knee bolster panel, you can pull it down and you will see the little finned sensor. Are your feet excessively hot? Maybe the sensor is hotter than the rest of the car because of the toe box?

Glad to hear it's not in a hard to reach place Mark. I'll get under there and look, I picture maybe a plastic Baggie wrapped around it or it being greasy and not reading right. I'll jiggle the wires too. My feet aren't hot at all so I think it's a hardware issue not software.

Thanks.

My old 2006 SRT8 300 had the snesor right in the dash just above cup holder level. If you had a hot coffee in the cupholders it would crank the A/C. Sound slike our Vipers have a completely different sensor. Good luck.

This is why I much prefer a good old-fashioned control knob. Hope you get it sorted.
