The purpose of this bulletin is to:
This section of the bulletin is intended to aid in sunroof actuator (motor) diagnostics. This information is in addition to the service information available in the S-Series service manual.
MODELS AFFECTED | SYMPTOM | POSSIBLE CAUSE | PROCEDURE |
---|---|---|---|
| Sunroof opens and closes but skips/hesitates when going from full open to close. | Actuator bull gear is stripped | Close sunroof and replace sunroof actuator. (Refer to the "Sunroof Actuator (Motor)" procedure in the appropriate S-Series service manual. |
Sunroof only goes to vent position and makes ratcheting/clicking noise. | |||
Sunroof goes to full closed and makes ratcheting/clicking noise. | |||
Sunroof goes to full open and makes ratcheting/clicking noise. |

MODELS AFFECTED | SYMPTOM | POSSIBLE CAUSE | PROCEDURE |
---|---|---|---|
| Sunroof glass panel is out of time on one side and will not close correctly resulting in a ratcheting noise | Sunroof actuator mounting bracket warped, causing actuator gear to catch only one cable. | Replace bracket and cable inset only. (Refer to "Sunroof Actuator Mounting Bracket Replacement" procedure in this bulletin). |
Sunroof will not open to full vent height | Sunroof actuator mounting bracket warped, causing mistiming of actuator vent setting. | Replace bracket and cable insert inside bracket. Re-time actuator to module before installing. (Refer to "Sunroof Actuator Mounting Bracket Replacement" procedure in this bulletin and "Sunroof Actuator [Motor] to Module Timing" procedure in the appropriate S-Series service manual.) |
This section of the bulletin is intended to aid in sunroof module diagnostics. This information is in addition to the service information available in the appropriate S-Series service manual.
MODELS AFFECTED | SYMPTOM | POSSIBLE CAUSE | PROCEDURE |
---|---|---|---|

This section of the bulletin is intended to summarize the sunroof components that can be serviced by following the service procedures in this bulletin and in the S-Series service manual. Based on recent sunroof warranty information, it has been found that sunroof modules/sunshades have been replaced when they could have been serviced with a component.
The following sunroof components are serviceable:
Sunroof glass seal is no longer serviceable Important
Do not replace sunshade due to broken slide blocks. Replace slide blocks using
sunshade kit. Important
If guide channel is fractured/broken, the cable end will most likely be separated
from the separated from the guide channel.Important
Tighten the locator block fastening screws to 2 N·m (17.5 lb ft)
Prior to removing sunroof/sunroof actuator, make sure sunroof glass is in full
closed position. this will result in proper actuator to module timing provided actuator
is not operated after it is removed. Important
Make sure sunroof actuator mounting bracket stays tight against drive tube
during rivet installation. Important

GM bulletins are intended for use by professional technicians,
NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to
provide information that could assist in the proper service of a
vehicle. Properly trained technicians have the equipment,
tools, safety instructions, and know-how to do a job properly and
safely. If a condition is described, DO NOT assume that the
bulletin applies to your vehicle, or that your vehicle will have
that condition. See your GM dealer for information on whether
your vehicle may benefit from the information. |
