We have a 2009 LR2 and the sunroof used to work when we first got it but now it seems to have stopped working (thankfully it's still closed)

I'm wondering if this is a common issue or maybe something simple like a blown fuse that I can easily fix.

I have some of the wiring diagrams and experience in electrical but due to the vehicle being a significant distance from where I live (daughter drives it), I was hoping to not have to do a ton of diagnosis to get it working again.

Thanks in advance for any suggestions or possible common issues with these!

 

It's fuse F10 here. If it blew it likely means the sunroof needs lubrication. The motor may be having to work too hard and drawing too many amps.

 

If the fuse is blown, replace it and try opening the sunroof while gently and symmetrically pushing it in the direction it normally starts to move (need a helper to operate the switch). If you get it partly open, lube as much of the mechanism as you can, close it and repeat until you can lube the whole mechanism. Then cycle it a few times to get the lube worked in.


*** If that doesn't work, the following is risky to the motor, safest thing would be take it to a shop...

If the 10 A fuse blows with no motion and you're sporting, you could replace the 10 amp fuse temporarily with a 15 amp. Then try the above. Replace the 10 amp once you get it partly lubed.

Do this on as cold of a morning as possible, and only try once for a couple seconds to minimize the odds of blowing the motor. Then let the motor cool down for 20 minutes before running it again.

 

Replacing a fuse that is blowing with a higher amp fuse is an invitation for a fire. VERY BAD idea.

 

I concur, this a bad idea. Track down the problem.

 

Sorry I haven't been back to respond to you guys. Thanks so much for the information. I will take a look at this fuse when I get to work on it again during our holiday break. Much appreciated and I'll reply back here after I have a chance to dig deeper into it. I'm guessing that the lubrication part is going to be the fix
