Unplugging The Cabin Sensor In The Dash Leaves Ac On Permanently. Cool?

I got an R33 Skyline. I was running the AC with the wire that goes to what I assume is the cabin temperature sensor in the dash unplugged (the mic looking port behind the windscreen wiper switches) and I noticed the AC no longer clicks on and of but rather stays on.

Normally when everything is plugged in properly my AC will click on and off every 30 seconds or so, even when set to 18 degrees, and I'm still hot. Just wondering if its ok to leave that wire unplugged.

I also remember reading a few other people having on/off clicking ACs as well.

With the sensor unplugged the air con will only blow cold air at 18 degrees. Every other temp it will blow warm air. The with the sensor unplugged it fails low, meaning its probably reading the temp as -45 degrees or so. Therefore no matter what it wants to warm the car up. 18 is always fully cold but

So no. You can't leave it unplugged unless you want to be annoyed with your air con from now on

Thx for the info. The issue ive noticed is even on 18 my ac switches on and of every 30 seconds or so when the sensor is plugged in. without the sensor it stayed on.

btw nice looking skyline. I kind of regret spraying my skyline boot badge black aka series 2 color coded. the white plastic makes the car look more elegant

The AC Compressor? It will cycle to pressurise the system as needed, if its cycling frequently you may need to get it re-gassed or checked out.

If its your Mix door electronic actuator (in car) then just ignore it, its working as it should
