Official summary
This bulletin announces a design change made to the HVAC control panels for the models listed above. The change will address customer concerns of the seat heater switches sticking in the ?pressed? position but not returning to ?flush? with the face of the control panel when released as shown in the photos below. A series of small air outlets (vents) has been added to the assembly to keep dust and dirt from accumulating and causing the switches to bind.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
