Sunroof does not open. Fuse is ok and the shade operates normally.


Do you know how to do automotive electrical testing ?????? How to read a wiring diagrams ???? http://www.bbbind.com/free_tsb.html .Videos on youtube Ohms Law Tech Tip from L1 with Dave Hobbs Copy of Voltage Drop Essentials TST Motor Age The only way to find the problem , testing !

Sunroof Description and Operation (One Connector System)
Sunroof
This diagnostic procedure is to be used for the 1 connector Sunroof System that combines the sunroof control module with the sunroof motor/actuator.
The Sunroof System consists of the following components:
• BATT MAIN 2 Fuse 50 A
• Body control module (BCM)
• RAP relay
• S/Roof Fuse 20 A
• Sunroof module (includes sunroof motor/actuator)
• Sunroof switch
The Sunroof System is controlled by the sunroof switch and the sunroof motor/actuator assembly.
When the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the body control module (BCM) applies a ground to the RAP relay in the instrument panel (I/P) fuse block. This activates the RAP relay and allows battery positive voltage to be applied through the SUNROOF Fuse to the sunroof module. Ground for the sunroof module is supplied from G302.
The sunroof can be placed in 3 preset positions:
• Open
• Vent
• Closed
When the sunroof switch is placed in the OPEN position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof motor/actuator then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the full open position.
When the sunroof switch is placed in the VENT position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof module then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the VENT position.
When the sunroof switch is placed and held in the CLOSED position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch close signal circuit. The sunroof module then applies voltage to the sunroof motor close control circuit and applies a ground to the sunroof motor open circuit. The sunroof motor then closes the sunroof.
The sunroof can be placed in any preferred open position when:
• The sunroof is in the fully opened position by pressing and holding the sunroof switch in the CLOSE position until the panel has reached the desired position then release the CLOSE switch in order to stop the sunroof
• The sunroof is opening, it can be stopped by momentarily pressing either side of the switch.
The sunroof control module, sun roof actuator, and the sunroof motor are integral parts of the sunroof module assembly and are not service separately.

Your best bet , take it to a qualified repair shop or buick dealer .

How do you reset sunroof in a 2001 Monte Carlo with 3400 model I


check fuse and relay if good than possible motor ot track problem their should be a mechanical bypass that will let you close it if stuck open the following information is courtesy of monte carlo forum
To check the condition of your original sunroof guides:
  1. Gl*** in closed position.
  2. Locate & remove 3 torx bolts on each side of sunroof glass. Lift glass out of sunroof opening & set aside in a safe place.
  3. Locate "J" shaped cover plate at front of sunroof track assembly. Remove 2 torx bolts from each cover plate.
  4. Lift up bracket to remove.
  5. Inspect the plastic guides on each side. The sunroof cables attach to guides on front outer corner. Inspect this area closely for damage.
  6. Do not operate the sunroof with the J plates removed.
Troubleshooting:
If the sunroof guides are not broken & the glass is a uniform height along the rear edge your problem may be a stripped gear inside the motor. The motor has a manual override:
  1. Get access to the motor by removing the map light/switch console or lowering the front of the headliner.
  2. Insert a large standard screwdriver into the nylon bushing at the center of the motor hub. Push up & turn the screwdriver to manually move the sunroof glass. If the unit will fully open & close manually, you most likely only need a replacement motor.

If your sunroof is stuck in the open position follow these steps to get it closed:
  1. Remove the glass.
  2. Try to close the unit without the glass. Many times one side will still be operational and close correctly.
  3. Try to slide the inoperable lift arm forward. If it moves, slide it forward until it stops.
  4. You now need to slide the original plastic guide forward to lower the arm to the closed position. Using a standard screwdriver, push it forward. The lift arm should begin to lower.
  5. If the lift arm will still not fully lower, remove the J plate as explained above, sometimes the sunroof cable will need to be lifted up to allow the guide to fully slide forward.
  6. Reinstall glass.

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 stuck


First off, you should leave it closed. At least you can drive it that way. The grinding could be the motor itself, or a gear inside that has rounded or broken teeth. Another possibility is that it has slipped out of a channel or track. Unless you're pretty handy this sounds like a professional repair job.

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.

Volvo V7 '01 sunroof will not stop in closed position


I think I know the answer....your gear has slipped on the cable a few teeth. Set the roof to the desired closed position, flush with your roof. Then open the panel above the mirror by first prying off the switch plate and removing the two 10mm bolts holding the mirror. Remove the sunroof motor gear, or rather just lower it out so it is disengaged with the cables. Now connect the switch and hit the auto open button as if you wanted to open the roof with single flick of the switch. Now hit the auto close button (same button of course, but the single touch method). The motor will advance and stop to where it thinks the roof should be, closed, which it is. Reassemble the gear into the slot, test it if all good, replace the mirror and panel.
Good luck.
Manfred.
