What Is This Plug For?

[dodes47]

After getting a Double Din Kit installed 4 months ago by Autotainment, my ac climate control started acting funny. I couldn't set it to Auto and the jump from 18° and 18.5° is very high. Other words it's either really cold or really hot.

I got told it might be the crappy Metra kit AC controller. So i was saving up to get a JDM one from Chris Rogers.

This morning i opened the bottom part of the steering wheel to reprogram my Swix-pac and noticed this cable and hose was unplugged. So i plug it back in then tested everything in the car. To my surprise the climate control works again! Unplugged it and it died again. I'm ecstatic that i dont have to get the JDM one after all $500 bucks saved for something else. Thanks anyways Chris

What is this bloody cable for? Why is there a hose connected to it?

I thought i'd post this just in case anyone is having the same problem.

AC sample tube. or in technical terms - inside cabin thermistor.

The hose and electrical connector together are part of the in-vehicle temperature sensor.

Yeh that connects to a thermstat that measures the temperature of the air con air as it passes (the hose contains air con air). The climate control then adds or subtracts heat based on this. If it is disconnected it obviously tells the system it is cold and thus the system directs the air through the heater on its way to the cabin.

Wow started this post when there wasn't any other replyies!

Aha! Makes total sense now.. I've been missing out on the climate control for months. Felt like there's a new addition to the car u know?

Thanks everyone
