Do some searching, try searching for +ETACS, or +doorlocks, +electrical.
I haven't had door locks, heat, working windows, working sunroof, heat, working interior lights, radio, heat, radio intena, speakers, in probably a month. And its getting colder by the minute here.
Weird thing is, I will do a real hard launch, or like nls to third, and everything will just start working, and then go away the next time I rip on it, or shut my car off.
