Sunroof on Volvo xc70 will not close

First check the fuse by looking at the fuse box, left side under dash, and look at the diagram on the back of the cover. It is kind of hard to orient the diagram sometimes, so use the spare fuses and large relays to orient. There will be description of fuse function on diagram and you can check/replace sun roof fuse. The sun roof probably has a relay and that may have failed.
