TECHNICAL
Subject:
Front Heated Seat Inoperative/Cold (Install Seat Heat Element)
Models:
2003-2004 Cadillac CTS with RPO KA1
Condition
Some customers may comment that the front seat assembly heat function is not operating properly. The front 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 heated seat back/cushion trim cover. The heated seat system consists of the two
front heated seats.
Correction
1.
Determine which heat element is not functioning properly by measuring the resistance values of the factory heat elements. Refer to the diagnostic
procedure 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 Service Heat Element Installation in this bulletin.
