Dorman - OE Solutions Seat Heater Pad P/N:641-107
If your original seat heater has gone cold, the Dorman seat heater pad 641-904 is a direct replacement for the front seat back heating pad, built to match the design and performance of the original. It fits many vehicles, among them the 2014-2018 Chevrolet Silverado 1500, 2014-2018 Chevrolet Silverado 2500 and 2014-2018 GMC Sierra 1500. See the "Vehicles it fits" section for the full list.
If a failed heater pad is the reason your seat back no longer warms, this pad replaces it. It is designed as a safe, effective and affordable repair that helps keep your seat comfortable.
Before you replace the pad, confirm it is the cause. A heated-seat switch, fuse or wiring fault can also leave the seat back cold.

What does the Dorman 641-904 seat heater pad do?
It is the heating pad for the front seat back. It warms the seat back when the heated-seat function is on and replaces an original pad that has stopped heating.
Which vehicles does this seat heater pad fit?
It fits many vehicles, including the 2014-2018 Chevrolet Silverado 1500, 2014-2018 Chevrolet Silverado 2500 and 2014-2018 GMC Sierra 1500. See the "Vehicles it fits" section for the complete list.
Will this pad work in the seat bottom?
No. This pad is for the front seat back position. The seat bottom uses a separate pad, so buy the position you need, or both.
What comes with the pad, and how does it install?
The pad includes a wiring harness that plugs directly into the existing connectors for plug-and-play installation. Follow the vehicle service information to remove and reassemble the seat.
What are signs the seat back heater pad may need replacing?
The front seat back no longer warms while the heated-seat function is on. A switch, fuse or wiring fault can cause the same symptom, so diagnose the cause before replacing the pad.
