Need some help on what direction to start looking at on this one ....so the other day I went to use my sunroof and it wouldn’t open pretty strange as I’ve never had this issue before after many tries I finally got it to open using the keys trick(lock,unlock,unlock) to open all the windows and sunroof as you can guess it wouldn’t close got it to close inch by inch using the reset procedure and called it a night woke up the next morning and the sunroof was opening and closing from the switch as if it never had an issue...worked for the entire day then the following day back to square one ...stuck closed and not making any noise no clicks nothing ....don’t know if I should look into a switch or maybe the motor ....checked the fuse and it’s fine so I’m pretty stuck as to where I should start....any help would be greatly appreciated

 

Since you are not in North America or Canada, the following wiring and configuration may be different to your model.

Driver's side under-dash Fuse No. 20 (20A) supplies the power (+) side to the moonroof open relay, moonroof close relay, and moonroof motor.

Ground (-) is supplied via the moonroof switch when used.

• Unplug the gray 12P moonroof switch connector, with a small paper clip or wire jump connector terminal cavity no. 5 (black wire) to terminal cavity no. 6 (lt blue wire) to see if the moonroof will open.
• If it opens, then jump terminal cavity no. 5 (black wire) to terminal cavity no. 8 (gray wire) to see if the moonroof will close.

If it works by jumping the connector, the switch may be faulty.

 

If it opened with the fob and not the switch replace the switch and you're done. We know it's not the motor because the fob was able to open it.

 

....thanks for the help I tried that today and unfortunately no luck I’m starting to feel like lit could possibly be the motor that’s gone bad but I’m not 100% certain ...checked the 20 fuse with a power tester and I’m definitely getting power down there so I’m thinking maybe the motors kicked the bucket ...any thoughts??

 

If the sunroof opened consistently with the fob how could it be the motor

 

Also It only opened with the fob after many tries and wouldn’t even close back with it I finally got it closed ...I even tried opening it with the fob today multiple times and only the windows roll down the sunroof stays shut

 

Only for one day after that no response again even today no response from fob or switch

 

Was there any work done on the car before this started happening?

What kind of tester are you using?

Unplug the moon-roof switch connector. Use you power tester to verify you have power (12 or 5 volts) on the purple, light blue, gray, and light green wires). Test the black wire for ground.

Supply ground to the gray wire using a jumper wire or power probe. That should close the moon-roof. Supplying ground to the light blue wire should open the moon-roof.

 

No work was done to the car before this started happening and I’m using a power probe to see if I’m getting power and it’s looking like I’m getting power only to the green wire...definitely ground coming from the black wire

 

My diagram is showing the green wire only goes to the connector to the moon-roof motor. Are you testing where the wire harness plugs into the motor or where it plugs into the moonroof switch?
