Mariner sunroof not working

Put the switch in the first detent for manual open/close

Most likely the fuse is burned out. Check the cars manual to find the fuse for the sunroof and check if it looks blackened.------------------------------------------------------------------------------

depending on the vehicle you may be looking at a bad sunroof motor, or the regulator(roof track and cables) could be bad, on some cars you can replace these things seperately, and on some you have to replace it all as one assembly. In most cases if you pull your headliner down so that you can see the motor there will be a manual opperation "port" usually a 1/4 or 3/8 drive ratchet opening so that you can manually close the roof until you get it fixed. In most sunroof motors I've seen the manual opperation port is either a red plastic circle with the ratchet drive opening in the middle, or there is a round plastic insert that you have to pull out to access the ratchet opening. hopefully this helps, if not try updating the question to include year make and model of the vehicle. Good luck!

These limits are not adjustable.

Sorry but that generally means a gear is stripped. The whole actuator assembly will have to be replaced.

if you remove the panel you will find an emer key underneath.adrian,,,,

does the sunshade open and close properly,you should only be able to move this when the sunroof is closed it should move freely back and forth,if it doesn't this part is causing the noise, its off its track
