Subject: INOPERATIVE INSTRUMENT PANEL LIGHTS
Model and Year: 1985 VEHICLES EQUIPPED WITH UX1 AND UT4 RADIOS
TO: ALL CHEVROLET DEALERS
Condition:

Some 1985 Chevrolet vehicles equipped with AM/FM stereo with seek/scan, cassette, and graphic equalizer (UX1 & UT4) may experience a loss of the instrument panel lights when the light switch is turned on.


Cause:

The condition may be the result of the right hand I.P. radio mounting bracket anti-rotation tab contacting the radio lighting bulb inside the radio.

ILLUSTRATION:

Correction:

Remove the right hand radio bracket and remove enough material from the tab such that only .050 inch (1.6 mm) material remains on the tab (see illustration.)
