SUBJECT: INTERMITTENT OR INOPERATIVE POWER WINDOW LIFT ACTUATOR MOTORS

This bulletin is being revised to correct the part numbers for the power window lift actuator motors. Please discard bulletin 88-10-55 and replace it with 88-10-55A.


Some 1988 Buicks may exhibit power window motors that start out as intermittent operation and eventually are inoperative. The motors are intermittent or inoperative due to restricted brushes making intermittent contact with the armature commutator.

If this condition exists, follow the diagnostic procedures in Section 8A of the Service Manual to determine if the switch, wiring, etc. is operating correctly. If the diagnostics show to replace the motor, replace with the following service part numbers:

VEHICLE WINDOW LOCATION SERVICE PART NUMBER

Electra/Park Avenue/LeSabre Rear 22062567 - R. H.
22062568 - L. H.

Regal Front 22087325 - R. H.
22087326 - L. H.

Parts are currently available from GMSPO.

IMPORTANT: Motors with date codes of 88/244 or higher should be used.
