I've been fighting this for 2 years, dome and trunk lights don't work as well as the power mirrors. Tried a new GEm and nothing changed, Took the lower dash out on the drivers side and found no indication there was a wiring problem there. I'm not even getting power to the fuse 35 which covers all 3 items.
