The Seat Shop is the AUTHORITY in factory match replacement leather seat covers, and we’re proud to offer a direct plug and play OEM style replacement seat bottom heating element for your 2003-2006 Chevrolet, GMC, or Cadillac full size truck or SUV! Do your heaters shut off after a few seconds? Do they fail to activate at all? The factory heaters are notorious for shorting out, and one faulty heater can cause the entire chain to fail. We decided enough was enough and developed our own! We extended the plug at the back, and implemented a higher gauge copper wire. By using current heating technology, we have created a seat heater that is less likely to short out, ensuring your seats stay warm and toasty for years to come!
