Bulletin Number: 10-90-19R; Revised: 07/10/19 Page 1 of 2
INTRODUCTION:
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.
PRODUCTION CHANGE INFORMATION:
This bulletin will be revised with the applicable VIN break information when it becomes available.
