I want to retrofit from the manual climate control to dual climate control but in the retrofit i have to put in a condensation senor but of course my car doesn't come with any sensor or wire which pin and which modules do i wire them up to and then what coding is needed if the car never had a sensor like that?

I need a new windshield anyways as mine has a few stone chips/cracks so i don't mind getting a windshield with the hole for the senor

I'm not sure what the condensation senor does or what feature will not work if non is installed.

I don't mind going through the trouble as much as i know it will be!

Any help or information would be highly appreciated!

You need to add Rain/Light sensor near the rear view mirror.
Add 521 and vo code.

Massive thank you! Any idea what it does for the dual climate control and where i could get wiring diagram?

This condensation sensor is located at the the base of the rear view mirror and is responsible for detecting moisture. If it meets a threshold it will turn on the compressor to begin reducing the likelihood of fogging the windows.
