Because your car runs on gas but your lites run on a battery.
there is a short in the relay for the head lights
you drain your battery when you leave your lights on
It wont start
It could be because its running out of battery
out of gas prbably
Car battery is run down.
Do the dash lights come on now that you have put in a new fuse...Does the motor rotate or try to turn over....If not, it sounds like you have a bad ignition switch....
even with the lights on, the battery may still be weak... try jump starting it, and see if it works...if not.. starter, ignition switch or other safety switch.. dave
yes but wont run for long, you will have no lights, horn, radio ect.
you need to specify a make and model and year of car but i would start by checking all of the fuses in the fuse box
If only the interior lights won't work, check the fuses.
Crank but not start and run, possible. Not to crank, start or run, no. No lights or horn, no.
