Info - Power Window Motor Now Available Separately From The Power Window Regulator Assembly

This bulletin is being revised to update information about window regulator availability. Please discard Corporate Bulletin Number 04-08-64-003 (Section 08 -- Body and Accessories).

This Service Bulletin is intended to inform technicians that the power window motor is now available separately from the power window regulator assembly for both the front and rear doors on the vehicles listed above. A failure of the power window motor in a front door should be repaired by the replacement of the power window motor only. Regulator failures will require the replacement of the window motor/regulator assembly. For power window motor replacement instructions, refer to the applicable Window Regulator Motor Replacement procedure in SI.

Important: The replacement of the complete front door power window regulator assembly, due to a power window motor failure, should not be performed as a warranty repair.

The rear power window motors are also available separately from the power window regulator assembly. The rear power window regulator assembly is not available without the power window motor. If diagnosis leads to a power window motor failure in a rear door, but the power window regulator still works, the entire power window regulator assembly should not be replaced as a warranty repair. Replace either the power window motor or the power window regulator. If diagnosis leads to a power window regulator failure in a rear door, but the power window motor still works, the entire power window regulator assembly will have to be replaced.

The front window motor part numbers listed below are applicable to vehicles from the 1999 to 2004 model years. The rear window motor part numbers listed below are applicable to vehicles from the 2000 to 2004 model years.

Parts are currently available from GMSPO.
