I just bought this car used. Everything is perfect but the sunroof won’t open or do anything. I don’t know if I need a new motor inside of the panel or maybe something wrong with the fuse or I would I need new tracks for the them?

Hi,

The first thing I would check is the fuse. There is one fuse that powers the roof. See pic 1. I also attached two additional pics that show the entire schematic for the roof functions. Note there are two motors and one switch. So, if the fuse is good and there is power both in and out from it, then we need to next check the switch. When you do check the fuse, if it appears to be good, confirm there is power to it.
