I've been highly researching to find a rain sensor for my 2012 LT Cruze because my car is equipped with the rain sensor fuse and gauge cluster light. My brother in-law works in parts at a Chevrolet dealership. I've actually contacted GM on this because we have searched and searched and can not seem to find this rain sensor part number. I heard back from GM with the part number 13231068 and the harness is PT2565. The harness plugs into the sensor but just has blunt wires coming from the other end. Current issue is I don't know how to wire it up. Are there wires tucked into the headliner?

That part number is actually for an Air Temp Sensor.
It's been a long time since I poked around in the ACDelco TDS system or even in the more detailed GDS2 programming, but to the best of my memory I never saw an option for a rain sensor for the Gen 1 Cruze.

Even if there is a spot in the cluster for auto-wipers and a place for the sensor to be mounted, the fact that there is isn't a programming option in TDS or GDS2 means there isn't a way to enable the functionality in the BCM.

These are the only active cluster indicators per the Chevrolet Cruze Owner's Manual. I checked both 2011 and 2012 versions and they are the same.

These are all of the alternate names that the sensor is called in the GM parts catalogs: Rain Sensor, Temp Sensor, In-Car Sensor, Cabin Air Temperature Sensor, Humidity Sensor, Sensor. That is why you were told it was the part you are looking for.

Your probably right i just don’t get why they would include in the indicator but never use it in any of their models. It’s also weird that GM said that it would work but if there is indeed no programmable option then it’s not going to work.

I'm not going to say with 100% certainty that it can't be done. It COULD be similar to the factory remote start option for the 2011 Cruzes - it exists but it can only be programmed into the BCM at the factory.
