Need suggestions. Lost all interior lights, all power windows and power mirrors. Checked all fuses, #4 is blown and when replaced blows immediately. I have taken the door panel off and checked all wiring, all was good; checked interior light wiring (we have the centurion package with infinity lights). I am completed stumped in this one!

 

If your vehicle has a lighted mirror on the passenger side visor, might be a good idea to check there.
