Condition
Some customers may comment that the radio does not turn on, is inoperative or that the display does not illuminate when the radio is turned on and the audio is operating properly.
Cause
GM Engineering is attempting to determine the root cause of the above condition. Radios that have been replaced for being inoperative or having no display have not exhibited either condition during the root cause analysis. There is a possibility that removing the radio from the vehicle and disconnecting the power will reset the radio.
Correction
Important
DO NOT attempt to diagnose or repair the radio. Avoid clearing codes or disconnecting the radio. If the radio is currently exhibiting this condition, it is very important that the radio is not disturbed.
Prior to attempting diagnosis or repair of a radio with this condition, contact a GM GM engineer with the details.
GM Engineering would like to identify vehicles that exhibit either condition in the Southeast Michigan region within 96 km (60 mi) of Detroit, Michigan, or the North Central Indiana region within 121 km (75 mi) of Kokomo, Indiana. If you do not receive a response from a engineer within two hours, continue with diagnosis and repair of the vehicle per SI.
