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.

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:
?€¢
No DTCs are set.



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


2. 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 !

most likely they control mechanism is a bit stiff/dry , if the roof will move forward spray wd40 up each side runners etc go back and forwards a bit at a time ,this should lubricate the mechanism and hope fully save ypou having the roof stripped out to solve the problem

There should be a crank on your fuse box cover {hexagonal section}. That is the manual closer for sunroof. You have to take off cover for readong/interior light to access the cranking point.

The only suggestion is to place the vehicle on
stands & remove the wheel to check out the issue

To speculate from the internet-- is just that.

To have something happen while you sleep
is odd,so I would be inclined to go with something
like an electronic parking brake issue,if that applies

1. Move the sunshade rearward to the open position.
2. Separate the mechanism covers (2) from the tabs (1) on the glass panel.
   
   
   
3. Verify the sunroof glass panel is in the fully closed position.
4. Loosen the forward attaching screws (2) on each side enough to permit the front of the glass to adjust up or down.
5. Adjust the front surface of the sunroof glass panel 0.00 mm to 2 mm (0.00 in. to 0.08 in.) below the top surface of the roof.
6. Tighten the front glass panel attaching screws to 5.5 N•m (49 in. lbs.).
7. Loosen the rear screws (2) on each side enough to make the rear adjustment.
8. Adjust the rear surface of the sunroof glass panel 0.00 mm to 2 mm (0.00 in. to 0.08 in.) above the top surface of the roof.
9. Tighten the rear glass panel attaching screws to 5.5 N•m (49 in. lbs.).
10. Check for proper fit. If not OK, repeat glass panel adjustment.
    
    
    
11. Position the mechanism covers (2) over the glass tabs (1) between the locating features and seat fully.
12. Verify sunroof operation and alignment.
    

There is a reprogramming from chrysler for the sunroof for recalibrating the sunroof for flushness also. the dealer will charge for this .You might want to do this first and then the adjust if not satisfied with the results.

It can be faulty motor or loose wiring issue or faulty /weak sunroof controlling switch or there is some blockage for sunroof to come down to close or sunroof out of its track the headliner is out of its way.There re many possibilities.All this basics needs to be checked.For further troubleshooting,go through this help link:----

Thanks.

well your best bet is to go to a pro this is not something you can do at home the sun roof needs to come down to be serviced not easy cause it does wiegh quite a bit and most of the roof needs to be taken apart some what costly aswell sorry to say

It sounds like it just needs to be reinitialized. Turn your key to the on position with motor off and hold the up/full vent button down for at least 30 seconds or until your sunroof either clicks or goes to the full vent position. That should fix your problem.
