Hey Guys,
Ok so let me start by saying, I've searched everywhere and tried a few different things and still have the issues.

Ever since I changed out my battery, my sunroof has been giving me issues.

1. The auto open works perfect for going up as well as opening all the way
2. The auto will not close the sun roof, I have to hold down the button until it fully closes.
3. On the close ( both fully and from a upward position) the sunroof will move and sound with multiple clicks.
4. Motor sounds perfect just feel like it needs to recalibrate, sort of like the windows.

Any help would be amazing
Thanks

Sunroof needs a reset. This should solve your problem.

Here is how you reset.

Close all your car’s doors.
Put the key to position II.
Don’t start the car.
Open the sunroof all the way. It may require that you press the sunroof open switch several times.
Once you reach the fully open position, continue to HOLD the sunroof switch in the OPEN position until hear a click. If you don’t hear the click make sure to hold the switch for up to 5 seconds.
Next, close the sunroof and again hold the switch for 5 seconds when you reach the closed position
Check if the problem has been fixed. If not, repeat steps 4 through 6.
You may also try these steps:
With your key in position 1 or 2 and all doors closed, press the sunroof button to the tilt position and hold it for 5 seconds.
Push the button towards the rear seats and hold it for 5 seconds.
Push the button forward and hold again for 5 seconds.
Push it toward the bottom and hold it for 5 seconds.
Check if the sunroof is working properly again. Repeat steps 1-4 as needed.

Perfect timing on this as mine is doing something weird also. Opens and closes fine but when opened at tilt it is fine also but when I press the button to close it after tilt, it moves a slight bit and makes a click/clunk sound. Press the close button again and it closes just fine.


I'll try a re set and see if that works.

Just went out to the parking lot here at work and tried the reset.


1st part did not fix my issue but the 2nd portion did.


Here is what I did in case others experience the small issue I was having.

With your key in position 1 or 2 and all doors closed, press the sunroof button to the tilt position and hold it for 5 seconds.
Push the button towards the rear seats and hold it for 5 seconds.
Push the button forward and hold again for 5 seconds.
Push it toward the bottom and hold it for 5 seconds.
Check if the sunroof is working properly again. Repeat steps 1-4 as needed.
