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 either the HEAT/OFF switch or the BACK ONLY 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. On the DHS and DTS models, each heated seat consists of four
heat elements, one in the seat back and three in the seat cushion. On the DeVille model, each heated seat consists of two heat elements, one in the seat
back and one in the seat cushion.
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 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.
