The sunroof on my 2006 Infiniti G35 Sedan will not retract (open) into the roof. It will tilt up and down without issue, and it will begin to retract, only to hit the physical limiter switch almost immediately. The motor seems to be running fine, and the clutch seems to engage without issue. I could not find similar symptoms on any of the Nissan/Infinti forums I frequent.
I removed the glass and interior sunroof cover/shade, and was able to see that the limiter switch is not moving back when the 'open' button is pressed. I am able to move the limiter switches (and the rest of the mechanism) by hand, but I have to pry a piece of the switch out of a groove in the tracks before they will budge. There does not appear to be any mechanism that should be doing that prying during normal operation, so I'm confident that is not the issue.
I am unable to turn the motor using an allen/hex key, even with the motor removed from the assembly (I put as much pressure on the 4mm key as I am willing to risk, to no avail.)
I tried the 'reset sunroof limit' procedure from Nissan/Infiniti, but it encountered the same limit switch problem. I also tried lubricating all visible tracks, pivots, and joints with silicone grease.
What could be preventing the limit switch from moving? Can anyone find detailed drawings of a Nissan sunroof system to aid in my troubleshooting? I have read there is a cable that pulls the limit switches back, but the motor is in the front, and there doesn't seem to be anything other than rails at the rear of the assembly. Pictures of the sunroof mechanism tell the same tale.
EDIT: I'm not great with wiring diagrams, could whatever leads to the 'comfort stop' on the diagram below be the problem?
EDIT AGAIN: I checked all 3 fuse boxes and couldn't find anything that said sunroof, and none of the fuse boxes seemed to correlate to the fuse diagram shown below.
6/20/16 EDIT: Finally got my roof rack off and dug into this problem again, tried a new motor from the junk yard and it hit the same problem.
This isn't important enough to sink serious money into, but it's summertime, and I want a working sunroof dammit!
