This almost has to be a bad switch. Replace the switch and it should work correctly. It is on the column then the it is not so easy. Have someone do it. If it is on the dash these are pretty simple. Just unplug them then unbolt it then replace. Good luck.
alternator
headlights and dash lights in 2001 sunfire wont turn on.
Dead battery and/or alternator.
You have to go to the dealer and ask them to turn them off, otherwise they leave them on as running headlights. They will do this for free.
Replace your headlamp switch.
that means your battery will be dead in the morning
If your regular headlights wont turn on but only the brights for your Monte Carlo 07 then you're probably experiencing an outage in the light area. The fuse or the bulbs may also be the cause of the problem.
its got to be two things either your headlights or the headlight switch, theres no relay so straight power from the battery to the switch to the headlamps. just change your headlight and it should work.
not enough information is really given here, what engine? is it cranking over (meaning when you hit the key does the engine turn)? do you have fuel? do you have spark at all plugs? is the fuel filter clogged? is fuel getting to the injectors?
There is probably some debris laying next to the plug that is keeping the socket form going on.
try e brakes..turn the e brakes on and see if it turns off.if it does then you have suto headlights
check dimmer switch for headlights
