Thank you all for the quick response. I replaced the switch but the vista still wont run. i can be for sure if i am getting power to the switch. I am getting 12v across the fuse terminals and i have tried a couple fuses still nada. There is no noise from the motor and neither the roof or the shade will open. I will continue to to look for a wiring diagram of the sunroof. but so far nothing has come up. I may have to go to the dealer and get a print out of it.
