Diagnostic Information on Inoperative Heated/Cooled Seats

The purpose of this bulletin is to provide dealers with information to help diagnose inoperative heated/cooled seats (seat cushion, seat back or both).

Verify that connections to the heat/cool seat module (1), which is located under the passenger side seat, are fully seated.

Verify that the black 8-way connector (1) is fully engaged. To gain access this connector, remove the plastic seat back panel. The connector is located just above the blower.

Attempt to pull the mating connectors that go to the blower and seat back harness apart WITHOUT depressing the release lever. If the connector disengages, force the connectors together until a "click" is heard and the connectors can no longer be pulled apart without depressing the release lever.

Verify that the black 8-way connector (1) that connects the seat wiring harness to the blower takeout is properly seated. This connector is located under each seat and can be accessed from the rear underside of the seat.

Force the connectors together until a "click" is heard, and then attempt to disengage the connector without depressing the lever release. If you are unable to disconnect, a full connection has been attained.
