This is a Genuine OEM GM A/C and Heater Climate Control Module for the 2020–2021 Cadillac CT5 and 2021 Cadillac CT4. It restores full operation of your vehicle's heating, cooling, and automatic temperature control system.
This is a genuine GM OEM part designed, engineered, and tested to rigorous factory standards. Fits vehicles equipped with Automatic Temperature Control and a 2.0L L4 Turbocharged (LSY) engine. Multiple variants exist based on vehicle options such as heated and ventilated seats — you must verify that this exact part number matches the labeled number on your original unit before purchasing. Professional programming to the vehicle's VIN using GM-specific software is required after installation; this part is not plug-and-play.
