Lights!!!!!

thanks guys. Its not like I have not checked. the cigarette lighter has power but will not
heat the fillement. the dome light has power, but will not come on. the left door switch
has power, but dome light does not come on.
For those that read my posting, I had headlights, side marker lights and tail lights.
yesterday morning, later I had none.
I did the carpet myself and made sure there were no wires damaged.
this is just a gremlin. sometimes I have a horn other times no, no 4 way flasher ever
I have a 73 Chrysler service manual and I am using the Valiant wiring diagram which
looks just like the 74 Dart, way better then the Haynes
Well it looks like the next few days will be fixing (all) electrical problem.
Best

If you have power at the door switch and ground that wire to the body you should have a dome light come on. (That's all those switches do is supply a ground to the body when the door opens)
Those switches can look like they work, but not make the contact.
I just replaced both of mine because that was exactly the case with them.
