ok so the other day i had to pull the controls for AC, Fan, Temp about nav screen and somehow i broke the connector for the smallest of the plugs on the left side of the unit if your looking down at it while its still connected to the car. does anyone know what this goes to or where i can find that info? Also where can i get a replacement connector, i just want to make sure i get the right one? I can open it up and take a pic if needed.

I'm wondering if this plug being disconnected would cause the temp of my air not to change really at all but it defiantly dont get hot at all and from what i know the heat and everything was working before pulling unit out breaking connector.
This isnt my unit but the same one, im pretty sure connector i broke was from the smallest of the connects back there, the 1 on the left in the top pic.

Take a picture of broken connector.

That connector runs all stepper motors that adjust temperature and air flow.

I think it is this one. It is 4 pin MQS but only 3 pins are used.

ok i will pull it back out later today, in the top pic from my original post its the plug on the far left. So could this be why my air temp isnt changing or is my heat issue likely something else?

in the top pic from my original post its the plug on the far left.

See if you can retrieve part # from harness will help to identify associated connector:

Ahh good looking I didn't even think about doing that.

Go to a self-serve wrecking yard and get what you need to repair the connector.

The ends of the wiring harness are available from the dealer at very low cost. Go ahead and consult with your local dealer and get a new part.
