About 12 years ago, I installed two fans in my kids bedrooms. Both the same brand just different look (girls room white) (boys room oak). Recently my daughters light fixtures on the celing fans, stopped working. I did a quick check of the wiring to make sure it wasn't just a fuse in the lights or something. (This unit didn't have replaceable fuses) I decided to purchase a new switch, since the fan worked but the 3 lights didn't. Well the fan did run smoother, however the lights still don't work. OK, I thought I'll put the switch in my son's room, his lights work! Well after doing that, his fan works but the lights don't anymore. Even after putting the old switch back on. Could I have a grounding problems somewhere. Both rooms are having the same problem, so could it be in the breaker panel? Any help is appreciated.
