Customer States: The lighting on the buttons for the front A/C display control head will occasionally flicker. During these episodes the control head will not accept any input. Workshop Findings: While this symptom is sporadic in nature, it is possible to reproduce.

A key cycle normally restores operation. Production Solution This bulletin will be updated when more information is available. A solution is currently under development. Service No repairs are necessary at this point. Do not replace any components for this condition since this will not resolve the customer’s concern.
