Flash: Front Defrost Button Does Not Respond At Times
This bulletin involves selectively erasing and reprogramming the HVAC control module with new software.
Customers may experience a situation where the touch screen climate controls may ignore the first press of the front defrost button if it is the first climate button pressed after ignition
ON. The second press of the front defrost button works correctly. If another climate button is pressed prior to the front defrost button, then the control will respond as desired.
