my uncles truck has a issue with the sunroof not working. i checked the fuse for the sunroof and it looked fine but replaced it anyways. nothing change so then i checked the power at the fuse and there is 13v, so all good there. i then popped off the trim piece that holds the switch and then tested all wires there. there was no power at any wire that was going into the switch. where does it go before it enters the switch? after testing the wires i then popped out the sunroof fuse and tested to make sure i did not blow it and it tested fine. he said it worked fine then no longer worked. any ideas?
