Try to start my car today and it won't start. Turning the key all the way to start the car just makes a clicking noise and all of the interior lights go dim. Same is true if I turn on the accessory switch and run the headlights. If I turn on the accessory and press the brake pedal, the radio and all lights turn off for a second then turn back on.
How can I start my car? I'm stuck at friend's house for today. I really want to go home!
Sounds like a dead battery. Have your friend help you jump start it or if you have a manual, push (compression) start it. Instead of going home, go have your battery and charging system checked so you don't get home and get stranded.
You might simply have a loose battery terminal or it may be time for a new battery or alternator.
