You should check power to the sunroof motor. See if it is getting power. If it is, then the motor is shot, If not, then the problem may be in fuse, wiring, or relay

Here's a description the sun roof
Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof module
• Sunroof switch
• Sunroof motor, with 2 hall effect sensors and limit switch
• Sunroof window
• Sunroof sunshade panel
• Power supply for the sunroof module: RAP 25 A
• Ground G402

Override
The override function is used when needing to force a closing of the sunroof window. To override the system:
Turn ignition to ON.
Rotate the sunroof switch to the close position.
Press upward.
The sunroof switch data 6 circuit, or override circuit, will become grounded at the sunroof module. As long as the sunroof module sees this input, it will continue to slide the sunroof window to close, regardless of the other sunroof switch data circuits inputs.

Sunroof won't close automatically.


Is the motor receiving power? If not you have to check electrical system to locate the place that is not transmitting power. Could be a fuse/relay, switch, bad connection.

If the motor is turning and nothing happens then the drive mechanism from motor to sunroof is stripped. Not good.

2001 cadillac deville sunroof open and want close


Check the RAP fuse in the rear fuse box , this fuse powers the sunroof control module ! Fuse Block - Rear , Left rear of the passenger compartment, under the rear seat .
The sunroof module contains the logic for the opening and the closing of the sunroof. The sunroof motor assembly contains the reversible DC drive motor, the gear train, and the limit switch.
The sunroof module determines the sunroof motor direction based on inputs received from the overhead console sunroof switches. When the ignition switch is in the ON position or when retained accessory power (RAP) is active, voltage is applied to the sunroof module via the RAP relay. For a description and operation of the RAP system, refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power. The sunroof module controls the sunroof motor direction by changing the polarity of the applied voltage. The sunroof module remembers the sunroof position whenever the ignition switch is turned to the OFF position. The limit switch is used as an input to the sunroof module to indicate that the glass is fully closed, or in the comfort stop positions. The limit switch is grounded when the sunroof glass is in the fully closed or comfort stop positions, otherwise it is open.
The SLIDE CLOSE mode is initiated by moving and holding the sunroof slide switch (ROOF) forward. This applies a ground provided from the sunroof limit switch low reference circuit to the sunroof switch close vent signal input of the sunroof module. The sunroof module controls voltage to the control circuits of the sunroof motor. The sunroof motor will run until the limit switch contacts are closed. The closing of the limit switch will apply the sunroof limit switch low reference circuit to the sunroof limit switch soft stop signal circuit to the sunroof module, indicating the flush closed position has been reached. As the sunroof is approaching the close position the sunroof glass will force the wind deflector downward.
You need to have a factory scan tool hooked up an have it checked for DTC'S in the sunroof control module ! a code reader will not do this , a code reader will only check the engine codes for OBD 2 .
Important: The following must be completed before using the symptom tables.
  1. Perform Diagnostic System Check - Power Sunroof in order to verify that all of the following are true:
  2. ?€¢
    No DTCs are set.


    ?€¢
    The control modules can communicate via the serial data link.

  3. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation
your better off taking to the dealer !

Sunroof is stuck open and tried to reset it by holding button down for ten seconds and then it moves about half an inch and stays fully open. What do I need to do to get it to close?


Hi Thomas , First you should have it diagnosed by someone who has the tool to do so ! upscale scan tool , factory scan tool !
Diagnostic Starting Point - Roof
Begin the diagnosis with the Diagnostic System Check - Power Sunroof . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored DTCs and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
Symptoms
When no DTCs ( diagnostic trouble codes ) are present, begin symptom diagnosis by reviewing the
Sunroof Description and Operation . Reviewing the Description and Operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Roof in order to identify the correct procedure for diagnosing the system and where the procedure is located.
Important: If the suspected cause of an inoperative sunroof is a power interruption to the sunroof module, the sunroof must be re-initialized. Refer to Sunroof Motor/Actuator Synchronization .
Important: The following must be completed before using the symptom tables.

  1. Perform Diagnostic Starting Point - Roof in order to verify that all of the following are true:
  2. ?€¢
    There are no DTCs set.


    ?€¢
    The control module(s) can communicate via the serial data link.

  3. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation .
Visual/Physical Inspection
?€¢
Inspect for aftermarket devices which could affect the operation of the Power Sunroof system. Refer to
Checking Aftermarket Accessories in Wiring Systems.


?€¢
Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.

Intermittent
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to
Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Symptom List
Refer to a symptom diagnostic procedure from the following list in order to diagnose the symptom:
?€¢
Power Sunroof Inoperative


?€¢
Power Sunroof Does Not Open to Express Position


?€¢
Retained Accessory Power (RAP) On After Timeout in Retained Accessory Power, if the power sunroof should operate longer than 20 minutes after the ignition has been turned OFF


This information is right out of GMC service repair manual !
Sunroof Motor/Actuator Synchronization
Synchronization will be necessary anytime the sunroof module battery positive voltage circuit is interrupted. The sunroof module will be synchronized when the controller learns the full vent position. The sunroof system will ignore any open request until the system has been synchronized.
To synchronize the sunroof:

  1. Turn ON the ignition, with the engine OFF.
  2. Using the close/tilt up portion of the sunroof switch, operate the sunroof glass until it reaches the full vent position.
  3. Verify that the system operates normally.
Once the sunroof glass reaches the full vent position, the actual position is stored in the memory of the sunroof module. The sunroof module will stop the motor one motor revolution before the defined actual positions.

2006 honda ridgeline sunroof is stuck, will nor close tightly


Most common problem for sunroofs is debris like acorns, twigs, ect stuck in the track on the sunroof. Also, check for bent warped, or other out of place things causing the sunroof to reach it's limit causing it to shut down before closed completely. Remember, power windows, sunroofs, back glasses, nearly everything powered by an electric motor has a limit switch to protect if from damage.
