This bulletin supersedes bulletin T-89-70, Group 9, which should be discarded. It is being updated to include a new part number for the relay.
Some 1989 Cadillac DeVilles and Fleetwoods equipped with the Bose stereo may experience a condition of a loud pop when turning the ignition on or
the speakers "buzzing" with the radio turned off.
This condition may be due to a defective amplifier relay which causes the amplifiers to be powered when the radio is turned off.
The condition may be repaired by replacing the amplifier relay with a newly-available relay, PN 25537493.
The relay is located in position "B" of the interior relay center, behind the glove box.
