Front/Rear Heated Seat Inoperative/Cold (Install Seat Heat Element)

Subject:Front/Rear Heated Seat Inoperative/Cold (Install Seat Heat Element)

Models:1998-2004 Cadillac Seville with RPO KA1



This bulletin is being revised to update the model year, VIN numbers and includes rear seat information. Please discard Corporate Bulletin Number 01-08-50-002B (Section 08-Body and Accessories).


Important: This service bulletin includes rear seat diagnostic and part information.

Condition

Some customers may comment that the front/rear seat assembly heat function is not operating properly. The front/rear seat back and seat cushion remain cold when the HEAT/OFF switch is activated.

Cause

This condition may be due to a non-functioning heat element in the front/rear heated seat back/cushion trim cover.

The heated seat system consists of four heated seats, two in the front and two in the rear.

Correction

  1. Determine which heat element is not functioning properly by measuring the resistance values of the factory heat elements. Refer to the appropriate diagnostic procedure (1st, 2nd or 3rd Design, Front/Rear) in this bulletin.
  2. If the resistance values of a factory heat element are NOT within the specified range, install a service heat element between the non-functioning factory heat element and the seat trim cover. Refer to the Service Heat Element Installation Procedure in this bulletin.
