Got a 2001 S60 with a sunroof that is starting to get stuck on an intermittent basis. i think the swith is starting to go. Any website where I can go for directions to replace the swith before it cuts out for good??

 

Most likely it isn't the switch.
There is way more to the system than just the switch.

The rear view mirror is a module and it tied into the sunroof.
Also the alarm system it tied to it as well.
You might have a bad alarm siren.
