Item Condition

• Condition: Used, factory original.

• Cosmetics: Great interior cosmetic condition. The matte black faceplate finish is clean, smooth, and free of heavy sticky plastic degradation or deep trim gouges. The soft-touch control buttons and dual rotary dial caps retain sharp, crisp white factory icons with no heavy finish peeling or wear.

• Functionality: 100% bench-tested. All mechanical push switches click cleanly and respond immediately, the rotary dial resistors adjust smoothly across all zones without values skipping, and the localized backlighting LEDs illuminate brightly and evenly.

Key Features & Specifications

• Genuine Mopar Component: Guarantees an absolute flush structural alignment inside your Ram's center dash bezel with zero asymmetric aftermarket gaps or loose trim rattling on rough terrain.

• Corrosion-Free Contacts: Rear pin connector ports are clean, straight, and unmarred by terminal pin oxidation or moisture damage.

Network Sync & Proxi Alignment Advisory Note: Because this climate controller functions as a smart node on the truck's CAN-bus network, plugging it in may occasionally cause your vehicle's odometer to flash or result in mismatched blending behavior until the truck recognizes the new serial number. If this occurs, an automotive technician or dealership will need to execute a quick "Proxi Alignment" configuration or manual blend-door calibration script using a standard scan tool (like AlfaOBD or WiTECH). Always isolate your truck's 12V battery ground terminal prior to disconnecting the rear wiring harness to prevent localized data bus shorts.
