Re: i can't get my sunroof to close. my message board
Most likely the alarm siren module has failed. The alarm module is wired in series with the sunroof module. If the alarm siren fails (and it does) it will take the sunroof module offline with it.
What I would do is to unplug the module and cycle the key. If it is the siren module the sunroof will work. If it still doesn't work then it could be a wiring problem and would need to be taken to a trusted shop for repairs.
Here is a link to a website that will show detailed instructions on how to remove the alarm module.
Re: i can't get my sunroof to close. my message board
Hi there "mjones" I am having the same problem and I know it is because of a the failure of the alarm siren module. Where you say "Wahat I wouls do is to unplug the module and cycle the key" you mean to unplug the sunroof module or the alarm siren module? I would appreciate your feedback.

hold the vent button until the roof has "tilted" completely, then hold the open button until the roof has opened completely. the light that reads ASC should now be green and your sunroof should operate normally.
It may be that the glass needs to be adjusted and not the mechanism. Simply close the sunroof and from inside the car loosen the screws that hold the glass to the mechanism slightly and push up on the glass where it is low and tighten the screws while holding glass in position.(the brackets that the screws go through are slotted for this purpose). Open and close sunroof and check to see if it closes right. It may take a few adjustments to get it right. Hope this helps.
Some customers may comment that the sunroof will no longer respond to the control switch while in a vented, partially opened, or fully opened position.
A software issue with the sunroof control module may cause the sunroof control module to incorrectly indicate a "closed" position, which may result in no power to the sunroof motor.
Verify the customer concern. If a condition is present, replace the sunroof control module with a new sunroof control module, P/N 15847643. Refer to the Service Procedure in this bulletin.
Verify the customer concern by opening and closing the sunroof.
If the sunroof will not open , check the power windows.
If the power windows are also inoperative, check the fuse. If the fuse has opened, refer to Corporate Bulletin Number 05-08-64-004 to install 30A circuit breaker.
If the power windows are fully functional, refer to "Power Sunroof Inoperative" diagnostics (SI Document ID# 1392967) in the Body section of the 2005 Chevrolet Equinox or Saturn VUE Service Manual.
If the sunroof will open (or is already open), but will not close , proceed to Step 2.
Replace the sunroof control module. Refer to "Sunroof Control Module Replacement" procedure in the Body section of the 2005 Chevrolet Equinox Service Manual (SI Document ID# 1196049) or Saturn VUE Service Manual (SI Document ID# 1710479).
Open and close the sunroof in order to confirm that the customer concern has been resolved.
Sounds like the sunroof motor is out of time. Needs to be re-timed. There is a retime procedure, (that I would try first) but I don't remember the whole procedure. if you still have the problem, let me know and i will get the whole thing , from the service manual.
Hi. Check fuse 38 in the fuse box to the right of the dashboard. It is for the siren. There is a serial communication between the UEM and siren which if communication stops there it will stop power supply to sunroof module. Matt
some cars sunroof regulators come with a couple settings in sunroof
1 the 30 degree back tilt
2 half open stop sun roof
3 full open sunroof
these are common on sunroofs
now lets look at what could be the cause
bad regulator or needed greased gears
track needs to be cleaned which can stick the wheels down
most sunroofed vehicle regulators or gear boxes you will find in the trunk way up by the wheel wells in that little compartment tight to get out
also there should be a manual crank for sunroof placed somewhere in vehicle i know for my bmw it was back in the trunk on the gear box you will have to call dealer or look in manual to find sunroof manual crank and how to close
recommend taken to the closes dealer and have them service your sunroof mechanicals and have it cleaned up
sunroofs like cars needs to be cleaned on a certain milelage interval so that it will work for a long time
