Usually you need to pull down the head liner and the motor should be there

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.

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.

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.

How to install replacement sunroof motor on a 1999 Pontiac grand prix

The Vermeulen Hollandia tilt and slide sunroof on my 1996 Subaru Impreza has stuck open. We swapped the fuse for another one in the car and it closed. However, when we tried to open it again it stuck


First, were the fuses that you replaced the first BLOWN sunroof fuse with the same size? Example, 5 or 10 or 20amps...I am going to assume they were the same or you probably would have burned up the sunroof motor or just blown the replacement fuse real quick. Can you help the motor by pressing the palm of one or both of your hands against the inside of the sunroof glass and push the sunroof button while trying to help the sunroof slide back with your hand or hands. (Obviously if you use both hands someone else will have to push the sunroof button unless you have an extra arm and hand) If it slides back with the help of your hands, either the sunroof is sticking against the slide or the motor is worn down and just doesn't have enough strength to move it anymore. You could try to use a light coating of oil on the slides where the sunroof touches as it slides back and forth. Something like WD-40 preferabley but you could even use any motor oil, worst case "Cooking Oil". Good luck with my suggestions!!

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.

I have a 2002 Bravada and the sunroof does not work. There are no sounds and the switch was replaced and all fuses are fen, where is the motor for the sunroof located?


The motor for the sunroof is located in the roof typically under the head liner and trim. One additional thing you could do before ripping everything apart would be to check the voltage at the sunroof, before replacing the motor. If you have power than chances are you need a new motor. If you dont have power than you may have over looked a fuse or relay.

Take care
