So I forgot my lighter at home and used the car cigarette lighter , that's when my stereo, signals, tail lights, power locks, wipers, high beams, hazards and sun roof stopped all working .Now I've checked fuses replaced what ever fuses that were blown but still nothing!
I do have day time lights and my stereo is back to working. My horn is good and so are my windows and I just disconnected the cigarette lighter just cause I thought maybe if I leave it un hooked it won't do it again... So I in hooked the battery for a bit to see if it would reset but nope. Went and tried two new relays but nothing. I was told that it sounds like a short but not sure where to start. Others said bcm bit I want to try other methods before I spend anymore unnecessary money. Anyone else have this problem if so how do you fix it?
