Does it have a remote starter? Defective ignition switch?
becaus the 2004 Chevy impala does not have automatic lights and they have to be turned off manually
Its probably your timing chain or belt
There is a switch for that. It is in the dash illumination brightness control switch.
Climate control blower motor was the fix. The part cost 441 dollars.
A door switch may be broken or out of adjustment or the dome light switch on the dash is turned on.
this happen to me and turned out to be corrosion on battery terminal, clean them very good.
bad battery
There are several safety mechanisms for the Chevy Corsica. if you accidently left the car out of park when you turned of the car, in some models if your lights are left on it wont let you take out the key.
A 1986 Ford F150 starter won't stuff off when the key is turned off if the ignition switch is jammed. This will cause the start signal to be sent to the starter continuously.
occasionally wen they wont shut up
Generally automotive blower motors are designed to run on the lowest speed even though the heater is turned off. The purpose is to circulate fresh air into the cab.
most likely cause is the timing is advanced too much and isnt shutting off properly
