That part number is actually for an Air Temp Sensor.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?
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.
