After 2 days of 10 degree weather my interior lights are out. My Power Mirrors are out. The Bell chimes when I take the key out like I have left the lights on. I checked various fuses including 7,17,36 but all are fine. Anyone had this issue? Is it a Relay or Fuse issue I am unable to locate?

 

These are always tough, but I would start by trying to find if they share a common ground or power source. Then I would see if you are getting power to the socket (I would check interior lights as you can be in the warm truck)

 

Problem Solved! The Power Mirrors and Interior/Cargo lights ride on the #23 Fuse. Replaced and tested 100%
