Hi,
My sunroof is inoperative on my 2011 Chevrolet HHR.
I have checked the fuse and sunroof switch.
Any tricks changing the motor without removing all garnish mouldings and headliner or other suggestions.

thankyou1:

No trick. But be sure that's the problem before you start.

Hi,
Couldn't agree with you more (Make sure that's the problem - Removing the headliner is big job and several air bags to disconnect)
Do you have any suggestions if the problem is not the motor?
I have checked the fuse, checked the over head switch. I have even changed the fuse and switch in the headliner.
What else could be the problem be if it's not the sunroof motor?

Thanks

The fuse is #10 under the hood. There is an enable signal from the BCM. There are "vent open" and "vent closed" signals/switches. Ground is below the left rear turn signal.

Seems the only "computer" involvement is the enable signal wire. I tried to post a pdf of the schematic, but failed.
