I have no power to my sunroof and window vent switches. I have checked 30 amp fuse and it's good, and looked for the relay. All the information I can find says the relay is in the RPO relay box under the dash behind the passenger airbag. I found two relay boxes but neither one is the correct relay box. Below is a box diagram I found online. The two boxes under the oval cover on dash are the blower/flasher relay box and the lock relay box, and the power distribution box is located on drivers side under the hood. I can't find the RPO relay box. Is it located in the headliner? Thanks.
