could be the fuse, but the sunroof relay is above the sunroof switch attached to the motor, the relay is a possible answer to the sunroof not working.
NO, there is no sunroof fuse on an Infinti i30, if your sunroof stopped working disconnect battery wait 5min & reconnect to reset it or pull the relay out & put it back in (relay is on inside fuse panel). this is common on Infiniti i30 & Nissan Maxima's
What number is the ascertain relay
its beside the cigarette ashtray where stereo is.....
try an auto parts salvage yard
Faulty relay
In the head liner right by the dome light and sun roof control
big relay with numbers 377 controls wipers and works as main supply for others like windows sunroof ignition and starter.....
fuse-box under hood
try #12&13 fuse
Probably in the fuse panel which is usually on the left side of the dash. With the driver's side door open, you can see the panel cover in the end of the dashboard. Yes I looked in the fuse panel, there is not one indication sunroof, and all fuses are good and sunroof still will not work Mine doesn't have a sunroof, so it's hard for me to be specific. There may be a relay in the box mounted on the driver's side fender under the hood.
Connect the sunroof motor with the sunroof motor retaining bolts. Connect the sunroof linkage. Connect the wiring harness to the back of the sunroof motor.
