Humidity sensor ?
 

I have a 2012 300c with the auto climate control system. Regarding the Humidity Sensor, what does it do.? What is it's function.?

I'm on 2 Chrysler 300 Forums and I can't get an answer to this question. What's up with that?

there is no such thing as a humidity sensor temperature yes humidity no

I don't understand this . I have read posts regarding guys replacing their Humidity sensors and seen the procedure on u tube, etc . And then there are posts on various Forums re guys trying to troubleshoot their AC systems that talk a lot about the "humidity" sensor issue. What's up?

Humidity is the amount of water in the air. the car does not car how much humidity is in the air even in an AC system

Hello Tarhealcracker. Nice to see you here. It is a google free zone. Sure there is a humidity sensor, despite what Chrysler Tech says. I have noticed when the humidity is high, the compressor will kick in, even though I have not set the temp to call for AC. Note the attached wiring diagram bottom right corner....HUMIDITY SENSOR.

Back to my question, why does the car have a "humidity sensor" and what does it do?

The literature for my car describes the system as "Automatic Dual Zone Temperature Control with humidity sensor" quote/unquote. I must say Chrysler Tech that you are being less than helpful. Responding to your posts in order:

1. The car does in fact have a "Humidity Sensor".

2. I understand the definition of Humidity is the amount of water in the air.

Come on now. Are you putting us on?

Thanks for the response Polarzak.
I'm not sure what's going on with Chrysler Tech. He has been most helpful in the past and heaven knows we need as many pros as we can get on this Forum.

The integrated temperature humidity sensor factors humidity in to the climate control to use only as much A/C as needed. If the temperature outside is 80F and the humidity is 80 percent, the system will control the temperature to a lower level than if the humidity was only 30 percent.

Wow. Outstanding. So the AC has an algorithm it uses to promote temp vs humidity comfort. My guess is that "recirculate" is in the tool box as well.

Well thats what I get for being out of the dealer for 9 years they add new **** and I dont know it it lol

Where you able to get this resolved? I'm still experiencing issues with my Chrysler 300 my AC blowing Cold Air on Driver side an hot Air on Driver Side. Initially I was under the Impression it was an issue with the a refrigerant Pressure but its all good. I took it to Firestone and Replaced the Sunload Sensor and Re-circulation Actuator. None of this has resolved my issues. I purchased a Scan tool and its Displaying Two Codes U0140 Lost Communication with Body Control Module and P1009 Humidity Sensor Lin Bus Assembly. The Humidity Sensor was replace as well. All parts replace are exact part Number from OEM . Any Suggestions of why these are still showing up and does it affect the AC.


This for a 2014 Chrysler 300s V6

This is usually a problem with the blend doors the HVAC air system. The actuator motor for the door(s) may be seized or broken.
