Hello and welcome, there is no way to manually close the sunroof. try this procedure and let me know what happens?


Perform the Initialization/Teach Procedure any time the sunroof motor/actuator is removed from the sunroof.

  1. Ensure that the electrical harness on the headliner is connected to the sunroof.
  2. Press the sunroof switch to the open position until the window stops at the rear soft stop in the fully open position. Release the switch.
  3. Press and hold the switch in the open position for 10 seconds or more. The sunroof will stall at the hard stop and move back slightly to the soft stop position. Release the button.
  4. Within 6 seconds, press and hold the open switch. After an additional 3 seconds, the sunroof window will move toward the close position.
  5. Hold the switch until the sunroof window stops at the closed position. Release the switch.
  6. Verify the operation of the sunroof.

already found someone else's suggestion online while i was waiting to hold the button after it was fully open....and tried it and it did not work.

Tried all the above also...holding it for close to 20 seconds causes it to start coming closed even though the open button is being held but it still stops in the same spot, slided forward fully but not down. Did the turn off and on been at this for a few hours now.

Have no idea where the electrical harness you are refering to is, but this one has never been taken apart so anything and everything should be properly connected.

Ok, don't worry about the harness. this is a relearn procedure for the sunroof motor and module assembly. sounds like you are kinda stuck on this one. the ost common problem is the sunroof air deflector guide blocks is cause ng the problem. there is a repair kit that should be installed to correct this problem



Install newly designed wear plates and actuator blocks. The new wear plate has a bump-out feature added to prevent the mesh deflector from contacting the sunroof glass. Follow the procedure below.

  1. Slide the sunshade to the full rearward position.
  2. Cycle the sunroof window to the vent position.
  3. From the inside of the vehicle, remove the sunroof window screws on both sides.
  4. Lift the sunroof window from the opening.
  5. Put the sunroof track to the full rear position.

Remove and replace the wear plate.

while a appreciate you taking the time to answer being a girl and having no one here to take it apart, i am not likely to try repairing it myself. Was looking for quick tip or trick like to one earlier to at least get it to close for the night so i could get it looked at tomorrow....use that darn thing ALL the time, never been idle for long periods as soon as the sun it out i use it...i know the motor is fine because it would slide forward all the way if the motor were shot. It click when i try to push for the secondary close but that is it, thanks for trying anyway.
