Subject:
RADIO MAY LOCK UP WHEN BATTERY IS RECONNECTED (REPLACE STEERING WHEEL PAD)

Models Affected:
1991 PONTIAC 6000 MODELS W/UX1 RADIO


Condition:

The UX1 radio (non-CD player with steering wheel controls) may lock up if the battery is disconnected, then reconnected with the ignition key in the "off" position. This may also happen if the battery is dead, and the car is jump started.

Cause:

The steering wheel control pad assembly may not be compatible with the radio, for the above reconnect condition only, for some early built 1991 models.

Correction:

If this condition is found, replace the steering wheel control pad assembly with a new pad, P/N 16161352. Parts are currently available from GMSPO.

The following procedure will unlock the radio:

1. With ignition off, remove both the "RADIO" fuse in the fuse block and the "ARC RADIO" fuse in the convenience center.

2. Turn the ignition switch on. Install the "RADIO" fuse FIRST, then install the "ARC RADIO" fuse. The radio should now operate correctly.
