2006 Chevy Envoy Denali moonroof stuck open manually close


You mean GMC not Chevy ! Chevy doesn't make the Envoy . There is no way to manually close the sunroof !
Power Sunroof Inoperative
If voltage is not measured on the sunroof switch open signal or sunroof switch close signal circuits, the fault could be in the retained accessory power (RAP) supply voltage circuit, battery positive voltage circuit, or sunroof motor ground circuit. If the sunroof motor is not being powered, neither will the sunroof switch signal circuits.

Attempt to operate the sunroof through its full range of functions in order to verify that the power sunroof inoperative fault is present.
Does the power sunroof system operate normally?

  1. Disconnect the sunroof switch.
  2. Turn ON the ignition, with the engine OFF.
  3. Connect a 3-amp fused jumper wire to the low reference circuit of the sunroof switch harness connector.
  4. Connect the other end of the 3-amp fused jumper wire to the sunroof switch open signal circuit of the sunroof switch harness connector, for 3 seconds.

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.

How do I fix the sunroof that wont close


Sounds like the timing is out. Pull the headliner down enough so that you can get to the motor. Close the sunroof and allow it to stop where it wants to. Then remove the bolts holding the motor on, pull the motor out of the way of the gears and push the sunroof closed. Then remount the motor. It should work correctly after that.

1996 Jaguar xj6 sunroof will not close you can hear motor running, how can you manual close it?


If you remove any gear that is coupling it to the motor you should be able to slide it back to where you want. I would put gear back just to hold it in place and keep it from moving. But you do have to replace that gearbox for future operation.

1996 ford explorer sunroof wont close


This website shows it has manuals and online diagrams like that. Sometimes a dealer parts guy will run you a copy of a parts diagram. It is a 13 year old vehicle- a salvage yard may have something torn apart that you could see.
