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 â pressedâ position but not returning to â flushâ 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.
