SOURCE: sunroof will not close

If the motor is stuck, you can probably hold the switch to the forward position, and smack the roof. This may allow the motor to start working. I don't think there is any way to do it manually.

SOURCE: Sunroof motor and cable replacement

The motor is located in the recess above the near side wheel arch and is mounted on a small frame held in place by two 10mm bolts. In order to remove the motor you will need first to extract the sunroof cable that runs though it. What follows sounds complicated but is quite quick and easy. 1) Ease the sun roof back to half open, if the motor is not working just put a 17mm socket on the nut in the centre of the motor and hand crank it open. 2) Between the sliding metal roof and the headlining panel, about 10cm from the leading edge, are 4 pop connectors. Slip a large bladed screw driver between these and separate. 3) Ease the headlining panel forward and pull it up and out through the sunroof aperture. 4) Now close the sun roof, if necessary using the same hand crank method used to open it. 5) On the under side of the sliding roof panel at the rear in the middle you will see the end of the cable tube guide . Mounted at the end there is a metal butterfly mount located with two 8mm bolts. This mount is what actually holds the end of the cable to the sunroof bridge mechanism. Remove these two bolts and withdraw the whole cable forwards, again the hand crank can help here. Take care this cable will be filthy. Check the end for signs of teeth missing - if so replace and clean the motor gear box of metal shavings 6) Returning to motor - disconnect the electrical connector block. 7) To the front of the motor the sunroof cable tube is held in place with a clip. Push the tube end at 90 degrees to the motor body towards the outside skin of the car to un-clip and to disengage it. 8) to the rear of the motor you will see a similar exit cable tube. This time the the tube must be pulled at 90 degrees to the motor towards the car interior and when unclipped this needs to be moved away towards the rear to clear the motor assembly. 9) Once the two 10mm frame mounting bolts are removed the motor can be extracted 10) Check the health of the (replacement) motor gear box by removing the three 8mm bolts holding the steel backing plate in place. The large plastic driven cog can be removed by undoing the 17mm nut on the other side whilst holding the central spindle with a 6mm open spanner to stop it rotating. 11) Clean everything to a shine and re-grease liberally. 12) Reassembly is the reverse of the above remembering to clean the drive cable and re-greasing prior to reinstallation

Wifes sunroof is open and will not close. Checked fuse it has pwr, removed switch it does not have power ... a ground problem at the sunroof motor...where is that?


First off this is controlled by a module (computer) The switch would only have five volts . 5volt reference voltage from the control module . Not knowing how to test the electrical circuit's for this could be expensive . Short out the module or 5 volt ref. voltage circuit inside the module.
Your best bet , take it to a qualified repair shop . Look at a wiring diagram here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on body & accessories ,then under subsystem click sun roof . Then click search button then the blue link . Now tell me you under stand what's happening here .

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof Opening Position Switch (SOPS)
• Sunroof switch
• Sunroof motor/actuator
• Sunroof glass (spoiler type, with glass sliding above roof)
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power supply for the sunroof control module: SUNROOF 20 A fuse
• Ground from G302

Sunroof Opening Position Switch (SOPS)
The SOPS tracks the position of the glass through 2 limit switches:
• Soft stop limit
• Vent limit
The sunroof control module monitors the limit switches and based on the inputs determines the position of the sunroof glass. As a limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling down the 5 volt reference to 0 volts.
The sunroof control module understands the position of the sunroof glass based on the different input combinations through the sunroof limit switch soft stop signal and sunroof limit switch open vent signal circuits.

Power Sunroof Does Not Close
Perform the Initialization/Teach Process any time a new sunroof motor actuator is installed in the vehicle or any time an existing sunroof motor actuator is removed from the vehicle. Refer to Sunroof Motor/Actuator Initialization/Teach Process .

My 1999 Jeep Grand Cherokee Limited sun roof does not want to open.


If your motor is audible and your fuses and connectors are okay, you may have to take a close look at the plastic gear parts up in the roof. The nylon parts do wear out since they are in the roof and more exposed to different temperatures. If any of that mechanism fails then your sunroof will stop working even if the motor is still good. It is a bit of a PITA to get to it since you will have to remove the headliner to get at the mechanism and then identify the worn part and replace it CAUTION: The sunroof system is timed from the factory so that the motor shuts off automatically when the sunroof window reaches a certain position. Extreme care must be taken when removing the motor, timing may be thrown off causing possible damage to the sunroof system. Anytime the motor is removed from the sunroof assembly the sunroof glass panel must be in the FULLY CLOSED POSITION or the unit will be out of timing. The drive motor cannot be reset to the park position after being removed.
CAUTION: The sunroof motor should only be powered through the vehicle battery and sunroof wire harness. Applying power to the sunroof motor leads will cause failure of the control module.
Move glass panel to the fully closed position.
Move glass panel to the fully closed position.
Remove the A-pillar trim. (Refer to 23 - BODY/INTERIOR/A-PILLAR TRIM - REMOVAL)
Remove the B-pillar upper trim. (Refer to 23 - BODY/INTERIOR/B-PILLAR UPPER TRIM - REMOVAL)
Remove the C-pillar trim. (Refer to 23 - BODY/INTERIOR/C-PILLAR TRIM - REMOVAL)
Remove the D-pillar trim. (Refer to 23 - BODY/INTERIOR/D-PILLAR TRIM - REMOVAL)
Remove the sunvisors. (Refer to 23 - BODY/INTERIOR/SUN VISOR - REMOVAL)
Remove the overhead console. (Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE - REMOVAL)
Disconnect the control switch wire connector.
Remove headliner as necessary to gain access to sunroof drive motor. Refer to Headliner Removal and Installation for proper procedures.
Disconnect the drive motor wire harness connectors (Sunroof Drive Motor and Express Module).
Remove drive motor fasteners and remove motor from the sunroof housing

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 !

How do you replace the sunroof motor on a 2004 Subaru Forester


Just out of curiosity, is it the motor that is faulty or one of the guides has broken? what are the symptoms you are experiencing?
IF you have a diagnosis and it is in fact the motor, here's how you replace it.
1. Fully close the sunroof glass, disconnect batt negative.
2. Remove Roof trim
3. disconnect Motor harness
4. Remove sunroof motor mounting screw and nut.
After installing the new motor you have to reset the sunroof motor.

A tip to help diagnose if you are just guessing for inop motor
(1) Check fuse for blow-out.
(2) Check switch for improper function.
(3) Check motor for incorrect terminal voltage.
(4) Check relay for improper operation.
(5) Check poor grounding system.
(6) Check harness for open or short and terminals for poor connections.
(7) Check limit switch for improper operation.

Moonroof wont close all the way


Do you know how to test automotive electrical circuit's with a DVOM - digital volt ohm meter ? When adjusting the moon roof did you see any switches ? sunroof limit switch
Measure the reference voltage of the sunroof limit switch soft stop signal circuit at the sunroof control harness connector to a good ground.
Does the reference voltage measure near the specified value?
4.5-5.5 V
Notice: Do not open the sunroof glass past the full open soft stop position. Doing so may damage the sunroof assembly and or the roof top.
Connect a jumper wire to the sunroof limit switch soft stop signal circuit at the sunroof control module harness to a good ground.
Turn ON the ignition, with the engine OFF.
Using the sunroof switch, operate the sunroof system, not to exceed the full open soft stop position.
Does the system operate as requested?

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof motor with the limit switches
• Sunroof switch
• Sunroof glass-spoiler type, with glass sliding above roof
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power sunroof system circuit breaker: PWR WDO 25 A
• Ground: G204

Sunroof Limit Switches
The sunroof limit switches track the position of the sunroof glass through two limit switches:
• Soft Stop limit switch through the sunroof limit switch soft stop signal circuit
• Vent Stop limit switch through the sunroof limit switch range signal circuit
The sunroof control module monitors the limit switches and based on the input combinations, determines the position of the sunroof glass. As a sunroof limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling the 5 volt reference to 0 volts.
The sunroof control module monitors both sunroof switch input requests and based on the sunroof limit switch input combinations, will control an output to the sunroof motor, to drive the sunroof glass to the requested position.

Sunroof Motor
The sunroof has a bi-directional motor. When the motor is not operating both circuits are grounded. When the motor drives the sunroof glass in the direction from the closed to vent or vent to open position, the following occurs:
• Voltage is supplied to the sunroof motor open circuit.
• Ground is maintained to the sunroof motor close circuit.
When the motor drives the sunroof in the direction from the open to vent or vent to closed position, the following occurs:
• Voltage is supplied to the sunroof motor close circuit.
• Ground is maintained to the sunroof motor open circuit.
The sunroof control module is equipped with a timer circuit which stops the operation of the sunroof motor after 8 seconds.
