Hi,

It could be the switch or the sunroof module. What I need you to do is check to see if there is power out from the switch when you press the close option. The wire you will be checking is an orange wire.

I attached a pic below of the wiring. If there is power at the switch, confirm there is power at the module at the same wire. If there is, likely the module has failed. If there is no power out at the switch, then it's likely the switch failed.

Let me know what you find or if you have other questions.

Take care,
Joe
